The inverse function is \(h^{-1}(x) = (x + 4)^3\).
Explicación
## Step 1The given function is \(h(x) = \sqrt[3]{x} - 4\). To find the inverse of this function, we first replace \(h(x)\) with
, which gives us
.## Step 2Next, we swap
and
to get
.## Step 3Now, we solve for
to find the inverse function. We start by adding 4 to both sides of the equation to isolate the cube root term on one side. This gives us
.## Step 4To get rid of the cube root, we cube both sides of the equation, which gives us \((x + 4)^3 = y\).## Step 5Finally, we replace
with \(h^{-1}(x)\) to get the inverse function. This gives us \(h^{-1}(x) = (x + 4)^3\).
