Question
Let $f(x)=2^{x} .$ We will see in the next section that this function is one-toone. Find each value, always working part (a) before part $(b)$.(a) $f(3)$(b) $f^{-1}(8)$
Step 1
For part (a), we are asked to find the value of $f(3)$. This means we substitute $x = 3$ into our function. Show more…
