Answer: 16)
\bold{√(x)} (17)
\bold{(x-4)/(2)} (18)
\bold{√(x)-2} (19) 3x - 18

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{√(x) =y}

17) Given: y = 2x + 4

Swapped: x = 2y + 4

x - 4 = 2y


\bold{(x-4)/(2)=y}

18) Given: y = (x + 2)²

Swapped: x = (y + 2)²

√x = y + 2


\bold{√(x)-2=y}

19) Given:
y=(1)/(3)x+6

Swapped:
x=(1)/(3)y+6


x - 6 = (1)/(3)y

3(x - 6) = y

3x - 18 = y
