y=±xay = \pm\sqrt{\frac{x}{a}}y=±ax
Switch x and y, then solve for y
Two branches: positive and negative
They switch roles
Check if relation is a function
Two y-values for each x-value
Restrict domain of original function
y=xay = \sqrt{\frac{x}{a}}y=ax for x≥0x \geq 0x≥0
y=xy = xy=x
(b,a)(b,a)(b,a)
