replace f(x) with y
switch x and y
solve for y

bibby · Answer

here $ f(x) = \sqrt{(x^2 - 3)}$
 $y = \sqrt{(x^2 - 3)}$
 $x = \sqrt{(y^2 - 3)}$

what would our first step be?

anonymous · Answer

so square each side to get rid of the square root

bibby · Answer

noice, noice
so now we have $x^2 = y^2 - 3$

anonymous · Answer

yes

bibby · Answer

so, what would our next step be?

anonymous · Answer

-3 each side?
