Question

Which of the following are exponential functions? (Check all that apply.)
A. y = 1 + x
B. y = 1.2x - 2
C. y = 4.2(5)x
D. y = 5x - 72

Select all that apply

Answer 1

none...

Answer 2

No

Answer 3

I mean none, lol

Answer 4

I chose A,D..

Answer 5

Question: Does "C. y = 4.2(5)x" mean y = 4.2 * 5 ^x ? If so, C is the equation of exponential function.

Answer 6

Option A is a line. Option D is a line as it. If D is meant to be y = 5^x - 72, then D is exponential.
