Question

Describe how to find the inverse of the function:
$f(x) = \sqrt{x + 3}$​

Answer 1

Answer:

f(x) = x² – 3

Step-by-step explanation:

Lemme try

f(x) = √(x + 3)

y = √(x + 3)

y² = x + 3

y² – 3 = x

Cz we gonna invers that, we'ld turn x to y and y to x, so:

x² – 3 = y

Yeah, inverse of the function is y=x²–3
