The graph below could be the graph of which exponential function?
A. FX) = 2 (7)
O B. FX) = 2
C. F(X) = 2 · (0.5)
D. FX) = 2(16)
To distinguish it from other exponential functions, the exponential function f(x)=e^x is frequently referred to as the natural exponential function.
What is exponential function?The mathematical symbol again for exponential function is e^x. The word, unless specifically stated differently, typically refers to the optimistic functional of a real variable, but it may be extended towards the complex numbers or adapted to other mathematical like matrices and Lie algebras.
The idea of exponentiation, or repeated multiplication, is where the exponential function got its start, but more recent definitions—there are several that are equivalent—allow for it to be rigorously expanded to everyone real arguments, especially irrational values.
A. FX) = 2 (7)→ 6(a+8)
O B. FX) = 2→4(1+ 9x)
C. F(X) = 2 · (0.5)→(9m + 10) x 2
D. FX) = 2(16)→ 3 (2x + 4y - 15z)
Therefore, to distinguish it from other exponential functions, the exponential function f(x)=e^x is frequently referred to as the natural exponential function.

If a triangle has 2 sides of 8 and 11 what could the third side be
Answer:
Any value between 3 and 19 may be the measure of third side.
Step-by-step explanation:
If three sides of a triangle are a, b, and c, possible measures of the sides of a triangle will be.
1). a + b > c
2). b + c > a
3). a + c > b
If a = 8, b = 11,
1). 8 + 11 > c
c < 19
2). 11 + c > 8
c > 8 - 11
c > (-3)
3). 8 + c > 11
c > 11 - 8
c > 3
Therefore, by combining the given inequalities,
3 < c < 19
Any value between 3 and 19 may be the measure of third side.

Answer: Its a
Step-by-step explanation:
The value of [tex]x=3+\sqrt{5}[/tex] make the quadratic equation true.
Quadratic equation :Given equation is,
[tex](x-3)^{2}=5[/tex]
We have to solve above quadratic equation.
Expand above equation first,
[tex](x-3)^{2}=5\\\\x^{2} +9-6x=5\\\\x^{2} -6x+4=0\\\\x=\frac{6\pm \sqrt{36-16} }{2} \\\\x=3\pm\sqrt{5}[/tex]

ΔABC is similar to ΔFED. Answer the questions to find the length of DF .
1. Which side in ΔFED does AB in ΔABC correspond to?
Write your answer in the space below.
2. Which side in ΔFED does CB in ΔABC correspond to?
Answer:
1.AB are the first 2 letters in ΔABC. Similarly, FE are the first 2 letters in ΔFED.
Hence side AB corresponds to side FE.
2.CB are the last 2 letters in ΔABC. Similarly, DE are the last 2 letters in ΔFED.
3.AC corresponds to FD
4.The scale factor is 2 because you would take the sides in ABC and multiply by 2 to get the sides in FED
5.6 because it corresponds to CB and you would multiply the side of CB (3) by 2 and you would get 6
6.A^2+B^2=C^2 = FE^2+ED^2=FD^2 = 8^2+6^2=100^2 = square root of 100= 10
The side length of FD is 10

Complete the table below.
Answer:
column 1, (2 and 2)
column 2, (8 and 4)
Step-by-step explanation:
For the first one, y = 2[tex]x^{2}[/tex]. You would plug in 1 into x and since one times itself is one, you would end up with 2. For the next question, you would plug in one and find that two times one is two. For the next column, by plugging in 2, you would find that you would end up with 2 times 4 and thus, you would find the answer which is 8. Lastly, two to the power of two is 4. Hope this helped!

FIND TWO NUMBERS WHOSE SUM IS 21 AND DIFFERENCE IS 17
11 , 10
2 ,23
19 ,2
Answer:
19, 2
Step-by-step explanation:
let the 2 numbers be x and y with x > y , then
x + y = 21 → (1)
x - y = 17 → (2)
Add the 2 equations term by term to eliminate y , that is
2x = 38 ( divide both sides by 2 )
x = 19
substitute x = 19 into (1) for value of y
19 + y = 21 ( subtract 19 from both sides )
y = 2
The 2 numbers are 19 and 2
