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) $f(4)$(b) $f^{-1}(16)$
Step 1
The first part of the question asks us to find the value of $f(4)$. This means we need to substitute $x=4$ into the function. Show more…
