Answer 1

Answer:  16) $\bold{\sqrt{x}}$        (17) $\bold{\dfrac{x-4}{2}}$        (18) $\bold{\sqrt{x}-2}$       (19)  3x - 18

Step-by-step explanation:

Inverse is when you swap the x's and y's and then solve for y

16) Given: y = x²

Swapped: x = y²

                $\bold{\sqrt{x} =y}$

17) Given:  y = 2x + 4

Swapped: x = 2y + 4

            x - 4 = 2y

            $\bold{\dfrac{x-4}{2}=y}$

18) Given:  y = (x + 2)²

Swapped: x = (y + 2)²

               √x = y + 2

        $\bold{\sqrt{x}-2=y}$

19) Given:  $y=\dfrac{1}{3}x+6$

Swapped: $x=\dfrac{1}{3}y+6$

            $x - 6 = \dfrac{1}{3}y$

            3(x - 6) = y

            3x - 18 = y
