Question

If f(x) = x2, find the inverse of f.

Answer 1

Answer:

inverse -1

Step-by-step explanation:

Answer 2

Answer:

The inverse is ±sqrt(x)

Step-by-step explanation:

y = x^2

Exchange x and y

x = y^2

Solve for y

Take the square root of each side

±sqrt(x) = sqrt(y^2)

±sqrt(x) = y

The inverse is ±sqrt(x)
