Answer:
To determine the inverse of function f, change f(x) to y, switch x and y, and solve for y.
Step-by-step explanation:
f(x) = ![\sqrt[3]{8x} +4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8x%7D%20%2B4)
Change f(x) to y: y =
Switch x and y: x = ![\sqrt[3]{8y} +4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D%20%2B4)
Solving for y: x - 4 = ![\sqrt[3]{8y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D)
(x-4)^3 = 8y
y = 
Therefore: inverse of function f =
Answer:
The answer is x=24.
Step-by-step explanation:
This is a one step equation, so it is simple, as shown.
In order to isolate the variable, you need to multiply each side of the equation by the fraction's reciprocal. In this case, it is -4/5.
Thus, x= -30 x -4/5
All things said, the answer is x=24.
