Question

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

Answer 1

x^{2} /4

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

Answer 2

x^2 ÷4

Explanation:

f(x) = ( 4x) ^1/2

y = (4x)^1/2

x = y^2 ÷ 4

then, inverse fun. is x^2 ÷ 4
