Question

Please helppp meeeeee

Answer 1

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
