Question

Which functions in the table below give values that could not come from exponential functions?

more than one answer will work
(Graph attached )

A. g(x)
B. f(x)
C. h(x)
D. k(x)

Answer 1

h(x)

Answer 2

it represent an AP with standard difference .25

Answer 3

h(x) is the correct answer. The first two are exponential growth. The last one is exponential decay.

Answer 4

not D either?

Answer 5

yeah, D looks weird with that k(0) = 0... I'm thinking that's not an exponentional function either. You'd need k(0) = 1 for it to be true
