Inverse function of the function...? I’m slowly losing my mind...

Answer:
x^2 ÷4
Step-by-step explanation:
f(x) = ( 4x) ^1/2
y = (4x)^1/2
x = y^2 ÷ 4
then, inverse fun. is x^2 ÷ 4
Answer:
x^{2} /4
Step-by-step explanation:
Rewrite f(x)= as y=:
y= \sqrt{4x}
Then swap x and y
x= \sqrt{4y}
x^{2} =4y
y=f^(-1)(x)= x^{2} /4
