Find the inverse of f(x)=4-x^2. HELP!!

almond37 [142]

Answer:

$f^{-1}(x)=(+/-)\sqrt{4-x}$

Step-by-step explanation:

we have

$f(x)=4-x^{2}$

Let

y=f(x)

$y=4-x^{2}$

Exchange the variables x for y and y for x

$x=4-y^{2}$

Isolate the variable y

$y^{2}=4-x$

square root both sides

$y=(+/-)\sqrt{4-x}$

Let

$f^{-1}(x)=y$

$f^{-1}(x)=(+/-)\sqrt{4-x}$ -----> inverse function
