Answer:

The graph increases as it approaches -∞.

The graph decreases as it approaches ∞.

Step-by-step explanation:

f(x) = -x - 2x³ + 3x + 9

f(x) = -2x³ + 3x - x+ 9

f(x) = -2x³ + 2x+ 9

Look at the highest exponent(which is 3).

SInce the highest exponent is odd, that means that the graph approaches infinity in a different direction as per negative infinity. Since the highest exponent has a negative sign:

The graph is going UP as x-values get SMALLER ( To  -∞)

The graph is going DOWN as x-values get LARGER ( To  ∞)

Hence:

The graph increases as it approaches -∞.

The graph decreases as it approaches ∞.

Answer:

Since the degree is odd, the ends of the function will point in the opposite directions.

When using supervised learning, the fit() technique requires two arrays of training data, but unsupervised learning only requires one array.

After the model is initialised, the "fit" method runs the algorithm on the training data. That is all it does, in essence. Thus, the machine learning model is trained using the training data by the sklearn fit approach. In the manufacturing industry, the term "form-fit-function" (FFF) refers to a part's distinguishing features (a single component that goes into the final build of your product, typically kept on an item master).

model.fit(): fit practise data This accepts the data X and the labels y as two arguments for supervised learning applications (e.g., model. fit(X, y)). Function at Cost. The cost function for linear regression is the Sum of Squares of Errors with the lowest value. Calculate the squared error sum for each and every available line.

An equation that depicts a straight line on a graph is said to be linear line.

Linear refers to a straight line. Straight-line graphs called linear graphs are used to show the relationship between two values. The single straight lines on this graph assist to represent a result. The phrase "linear" refers to a straight line and excludes the usage of curves, dots, bars, etc.

A linear line can include more than one variable. Linear lines with two variables, for example, are those that have two variables in them. 2x - 3 = 0 and 2y = 8 are few examples of linear lines.

Step-by-step explanation:

The population grows exponentially as the population size increases because the growth rate per capita (per person) growth rate remains constant. The availability of resources will eventually stop populations in nature from growing exponentially.

An exponential function is defined by the equation f(x) = ax, in which the exponent of the input variable x is used. The exponential curve affects both the value of x and the exponential function. The exponential function, with the form, is a crucial mathematical function. f(x) = ax.

Population growth or decline that is ongoing and whose pace of change is inversely correlated with the total number of people in the population at any given time.

The sum of the reciprocals of the two numbers is 0.5

Let the two numbers be x and y such that

x + y = 10

xy = 20

In x + y = 10, x = 10 - y

plugging in in xy = 20

(10 - y)y = 20

10y - y² - 20 = 0

y² - 10y + 20 = 0

solving the quadratic equation gives

y = 2.76 OR 7.24

sum of the reciprocal of the numbers

As a result, after 130 miles Company A charges more than Company B.

A number, a variable, or both together with particular operation symbols make up an expression. An equal sign separates two expressions that make up an equation.

Here,

Company A Cost is equal to 0.80 m

Cost for Company B is 65 + 0.30 m.

In light of this,

A>B is true

when,

0.80 m > 65 + 0.30 m

0.50 m >65

m > (65 / 0.50)

m > 130.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things. The term "line" can also be used to describe a line segment in daily life that contains two locations that serve as its ends.

The points on the line are (-4, 5), (0,2), (4, -1).

The slope of a line that passes through the points (x₁, y₁) and (x₂, y₂) is (y₂ -  y₁)/(x₂ -  x₁).

To translate an entire triangle, you need to first identify the coordinates of the triangle's vertices.

calculate the vector of the translation by subtracting the coordinates of the original triangle from the coordinates of the translated triangle. Finally, apply the vector to each of the triangle's vertices to move the entire triangle.

1. Identify the coordinates of the triangle's vertices (x1, y1, x2, y2, x3, y3).

2. Calculate the translation vector by subtracting the coordinates of the original triangle from the coordinates of the translated triangle (x1T, y1T, x2T, y2T, x3T, y3T).

The value of u​ = 56.78 degree

Any triangle's three angles sum up to 180 degrees when added together. Therefore, the sum of angles A, B, and C is 180 degrees. Any triangle in the field of geometry has this property. This concept can be used to determine the measure of an angle or angles in which the degree measure is absent or not provided.

A, B, and C is 180 degrees

in a triangle <u- 40 degree <u+50 degree so <u is

<u- 40 degree

<u+50 degree

so

<u =

(u - 40 ) + (u+50 ) + u = 180

To answer, let's use the exponent rules, here x³ denotes "x multiplied by itself three times,"

Exponents, often known as powers, specify how many times the base number must be multiplied.

Exponent rules are principles that are used to simplify expressions using exponents. These principles are also useful in simplifying formulas with exponents that are decimals, fractions, irrational numbers, or negative integers.

An exponent is just a shortened way to denote repeated multiplication.  x³ (or "x to the third power") in algebraic terms denotes "x multiplied by itself three times," or x x x.

Power is a mathematical phrase that denotes the repeated multiplication of a value or number.

As an example, power 6³ explains how three times the number 6 is multiplied.
