Find the inverse of the function.

f(x) = x3 - 8

Step-by-step explanation:

To get inverse function , follow the steps

Replace f(x) by y

Swap the variables x and y. Replace x with y and y with x

, solve the equation for y

Add 8 on both sides

To remove cube , take cube root on both sides

Now replace y with f inverse

for b its (t) and c its (d)

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
