If f(x)= x3 -7÷2 find f-1 (x)

The inverse of given function is

Step-by-step explanation:

Explanation:-

Given function

let      y = f(x)

   ⇒ 2 y = x³ - 7

⇒      2y +7 = x³

⇒  

⇒

The inverse of given function is

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
