Question

Is f(x) = 3•5^2x-3an exponential function? If so, write it in the form f (x) = ab^x.

Answer 1

we have the function

`f(x)=3\cdot5^((2x-3))`

Simplify

`\begin{gathered} f(x)=3\cdot5^((2x))\cdot5^(-3) \\ f(x)=3\cdot(5^2)^x\cdot(1)/(5^3) \end{gathered}`
`f(x)=(3)/(125)\cdot25^x`

therefore

the answer is option C
