Question

QuestionLet f(x) = (3)x-3. What is f(1)?Provide your answer below:ƒ(1) =

Answer 1

SOLUTION

We were given

$f(x)=(3)^{x-3}$

We want to find f(1). f(1) means we will substitute 1 for x into the function, we have

$\begin{gathered} f(x)=(3)^{x-3} \\ f(1)=(3)^{1-3} \\ f(1)=3^{-2} \\ f(1)=\frac{1}{3^2} \\ f(1)=\frac{1}{9} \end{gathered}$

Hence the answer is 1/9
