Best ResponseYou've already chosen the best response.2okay cool same like last one (x+3)^2 is same as (x+3)(x+3) so apply the foil method to expand (x+3)^2 and then replace x with y and y with x

Best ResponseYou've already chosen the best response.0so i foiled (x+3)^2 I got x^2+6x+9 so if you switch the x and y you would get x=y^2+6y9

Best ResponseYou've already chosen the best response.2how he got the answer: take square root both sides

Nnesha

Best ResponseYou've already chosen the best response.2that's what he did: replace x with y and y with x 2nd) then take square root both sides to cancel out the square

Best ResponseYou've already chosen the best response.2yes \[\huge\rm \sqrt{ x}=\pm \sqrt{(y+3)^2}\] just in case if he isn't familiar with the absolute value

Best ResponseYou've already chosen the best response.0I guess he was looking for inverse relation since an inverse function doesn't exist. And yeah... \[y=(x+3)^2 \\ \text{ take square root of both sides } \\ \pm \sqrt{y}=x+3 \\ \text{ now if } x+3 \text{ is positive or zero } (x+3 \ge 0) \\ \text{ then } x+3=\sqrt{y} \\ \text{ and if } x+3 \text{ is negative } \\ \text{ then } x+3=\sqrt{y} \] \[\text{ solving each } \\ x=\sqrt{y}3 \text{ if } x+3 \ge 0 \text{ or solving the inequality we get } x \ge 3 \\ x=\sqrt{y}3 \text{ if } x+3 <0 \text{ or solving that inequality we get } x<3 \\ \text{ so we have } y=\sqrt{x}3 \text{ if } x \ge 3 \\ \text{ or } y=\sqrt{x}3 \text{ if } x<3 \] which you already said
