Best ResponseYou've already chosen the best response.0i thought you had to switch x and y. so you would have x=y^2 +2 then you subtract 2 so its x2=y^2

Best ResponseYou've already chosen the best response.0either way works you will still get f^1 = sqrt(x2)

Best ResponseYou've already chosen the best response.0the direcxtions say find ^1 and the doman and range of f (1) determine where f^1 is a function. and the problem is f(x) sqrt 3x

Best ResponseYou've already chosen the best response.0dont forget about the 3 x^2 = 3y (x^2/3) = y now what is domain and range

Best ResponseYou've already chosen the best response.0domain is all real. and range idk

Best ResponseYou've already chosen the best response.0good range is all possible yvalues since x is squared, all the negative x's we put in become positive right? so our y value is always positive
