1. determine if the function f (x)= 3^2x-3 is exponential. if it is exponential, determine the base, b, when the function is written in the form f (x)= ab^x.
a. the function is not exponential
b. the function is exponential with base b=3
c. the function is exponential with base b= 1/3.
d. the function is exponential with base b=9.

2. what is the end behavior for the graph of the exponential function f(x)= b^x when b > 1?
a. f (x)—> ∞ as x —> ∞; f (x)—> 0 as x —> -∞
b. f (x)—> 0 as x —> ∞; f (x) —> ∞ as x —> -∞
c. f (x)—> ∞ as x —> ∞; f(x) —> -∞ as x —> 0
d. f (x)—> ∞ as x —> 0; f(x) —> -∞ as x -> -∞
4. which statement describes a key difference between the graphs of f(x)= 5•e^x and f(x)= 5.5•e^x?
a. the graphs have different vertical stretches.
b. the graphs have different ranges.
c. the graphs have different horizontal asymptotes.
d. the graphs have different end behaviors.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

2y+y=5

add 2y and y

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
