Question

Hey, someone give me the answer as im not sure​

Answer 1

`{h}^( - 1) (x) = - (7x + 13)/(5 - x)`

Explanation:

`y = h(x) \\ y = (5x + 13)/(x - 7) \\ x = (5y + 13)/(y - 7) \\ (5y + 13) = x(y - 7) \\ (5y + 13) = xy - 7x \\ 5y + 13 - xy + 7x = 0 \\ 5y - xy = - 7x - 13 \\ y(5 - x) = - 7 - 13 \\ y = ( - 7x - 13)/(5 - x) \\ y = {h}^( - 1)`
