Question

Which of the following functions shown in the table below could be an exponential function? Check all that apply.

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

Answer 1

its g(x) the function is

\[f(x) = 2^x\]

e.g. \[f(-3) = 2^{-3} = \frac{1}{8} = 0.125\]

\[f(-2) = 2^{-2} = \frac{1}{4} = 0.25\]

\[f(-1) = 2^-1 = \frac{1}{2} = 0.5\]

you can find the rest if you need to
