Question

f(x)= √x+3. Find the inverse of f(x) and it's domain​

Answer 1

Step-by-step explanation:

f(x) = √x + 3

y = √x + 3

√x = y - 3

x = (y - 3)²

Hence inverse of f(x) = (x - 3)² and its domain is x >= 3.

Answer 2

The required domain of the inverse function F(x)= (x-3)^2 is given by ≥3

f(x)= √x+3

What is inverse function?

The inverse function can be defined as the transverse of function.

F(x) = y
y = √x + 3
x= (y - 3)^2

or
for inverse function
F(x) = (x-3)^2
The domain of function is given by greater and equal to 3

The required inverse function is F(x) = (x-3)^2 and its domain is greater and equal to 3.
