Mathematics

F(x) = 4x - 9

let f(x) = y, this implies that  x = f⁻¹(y)

y = 4x - 9           Let us solve for x.

4x - 9 = y

4x = y + 9

x = (y + 9)/4

Recall that x = f⁻¹(y),

x = (y + 9)/4

f⁻¹(y) = (y + 9)/4

That means that for f⁻¹(x)

f⁻¹(x) = (x + 9)/4

Hope this explains it.

The volume of a sphere is 36π cubic feet. What is the radius of the sphere? (V = 4 3 πr3)
MrRa [10]

radius = 3 feet

rearrange the formula making r the subject

\frac{4}{3} πr³ = V ( multiply both sides by 3 to eliminate fraction )

4πr³ = 3V ( divide both sides by 4π )

r³ = \frac{3V}{4\pi } = ( 3 × 36π ) / 4π = 3 × 9 = 27

take the cube root of both sides

r = \sqrt[3]{27} = 3
