Answer:

To determine the inverse of function f, change f(x) to y, switch x and y, and solve for y.

$\frac{1}{8} (x-4)^3$

Step-by-step explanation:

f(x) = $\sqrt[3]{8x} +4$

Change f(x) to y: y = $\sqrt[3]{8x} +4$

Switch x and y: x = $\sqrt[3]{8y} +4$

Solving for y: x - 4 = $\sqrt[3]{8y}$

(x-4)^3 = 8y

y = $\frac{1}{8}$ $(x-4)^3$

Therefore: inverse of function f = $\frac{1}{8} (x-4)^3$

<h2>Explanation:</h2>

Hello! Recall that you need to write complete questions in order to get good and precise answers. However, I'll try to explain this problem in a general way. The definition of polynomial functions states:

$A \ \mathbf{polynomial \ function} \ of \ x \ with \ degree \ n \ is \ given \ by:\\ \\ f(x)=a_{n}x^{n}+a_{n-1}x^{n-1}+\ldots +a_{2}x^{2}+a_{1}x+a_{0} \\ \\ where \ n \ is \ a \ nonnegative \ integer \ and \ a_{n}, a_{n-1}, \ldots a_{2}, a_{1}, a_{0} \\ with \ a_{n}\neq 0$
