Please helppp meeeeee

Answer: 16) [tex]\bold{\sqrt{x}}[/tex] (17) [tex]\bold{\dfrac{x-4}{2}}[/tex] (18) [tex]\bold{\sqrt{x}-2}[/tex] (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
[tex]\bold{\sqrt{x} =y}[/tex]
17) Given: y = 2x + 4
Swapped: x = 2y + 4
x - 4 = 2y
[tex]\bold{\dfrac{x-4}{2}=y}[/tex]
18) Given: y = (x + 2)²
Swapped: x = (y + 2)²
√x = y + 2
[tex]\bold{\sqrt{x}-2=y}[/tex]
19) Given: [tex]y=\dfrac{1}{3}x+6[/tex]
Swapped: [tex]x=\dfrac{1}{3}y+6[/tex]
[tex]x - 6 = \dfrac{1}{3}y[/tex]
3(x - 6) = y
3x - 18 = y
