If your really good at functions can you plsss help me with this function task plsss i am really confused and stuck



Show how you calculate the rate of change
for function A . (from the table)

Show how you calculated the rate of change for function B, (from the graph)

Answer:

A. 2

B. 3

Step-by-step explanation:

Remember that the slope of a function is rise over run, or change in y over change in x

The "formula" for this would be [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where you're plugging in the values of the corresponding points (x1, y1) and (x2, y2)

I know all the x's and y's seem confusing but it'll make more sense once we actually apply it

Let's actually start with function b, since there is a graph to help you visualize this. The slope is how many squares up the line travels after going right 1 square. For example, look at the point (1,1) and count how many squares up it goes until the next point (2,4)

Its 3 squares up! and from (1,1) to (2,4) we've moved to the right only one square

so per every 1 square to the right, we move up 3

3/1 = 3, so the slope for b is 3

Note that you can do this with any two points on this graph, so if you started with the same point (1,1) and this time you counted all the way to (4,10), you would find that for 3 squares to the right, you go up 9

but now we need to find how far up you go for ONE square,

so you would do 9/3 = 3

3 up per one square over!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

okay, now let's apply this to function A

for this next step, remember that this works for any two points on the line

you can see that when x is at 1, y is at 5, so that represents a point at (1,5)

there is also a point at (2,7)

now imagine in your head you are looking at line that goes from (1,5) to (2,7)

how far up does the line go? Because you are going from 5 to 7, it goes up 2. If you're working with bigger numbers you can simply subtract, like 7-5 = 2.

next we need to know how far over the line goes. The x values go from 1 to 2, so that means you move one square to the right. This makes sense because 2-1 = 1

so, per every 1 square over, you move up 2, and therefore the slope is 2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I hope this helps, let me know if you need some clarification :)

Makayla repairs home computers. She charges a base fee of $50 for each visit and $25 per hour for her labor. The total cost c(x) for a home visit and x hours of labor is modeled by the function rule: c(x) = 50 + 25x.

For the situation, write and solve an equation. Then, explain what your solution means. If you get stuck, try drawing a diagram on your paper.

The United States Geological Survey (USGS) is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States and prepare detailed maps of every portion of the United States at a scale of 1:24,000. James has a USGS map of the rural neighborhood where he lives and measures that his school is a straight line distance of 15 inches from his home. Rounding to the nearest tenth of a mile, how many miles is his school from his home in a straight line? (Recall that there are 5280 feet in a mile and 12 inches in a foot.)
