If f(x)= -1/2 x-3, find f^1 (x)

bearhunter [10]

F(x) = (-1/2) * (x-3)

y = (-1/2) * (x-3)
⇒ -2y = x - 3
⇒ -2y + 3 = x
⇒ x = -2y + 3

Thus f^-1(x) = -2x + 3

we know that

The volume of a cube is equal to

$V=b^{3}$

where

b is the length side of the cube

In this problem we have

$V=512\ in^3$

substitute in the equation and solve for b

$512=b^{3}$

$b=\sqrt[3]{512}$

$b=8\ in$

1/4 (6x+2) - 3x= -1/2 - 4 +2x
-1/4 (6x+2) +3x= -1/4 -4 +3x
(6x+2) = -3/4 + 5x .
x = 10/7
