Answer 1

2( y - 1 )/y+5

Explanation:

h (y - 2) = (2 + 2 (y - 2)) / (7 +( y - 2))

=(2 +2y-4)/(7 + y -2)

=(2y -2)/(y+5)

=(2( y-1))/(y+ 5)

Answer 2

`(2y-2)/(5+y)`

Explanation:

Given function:

`h(x)=(2+2x)/(7+x)`

To find h(y - 2), substitute x = y - 2 into the given function:

`\begin{aligned}x=y-2 \implies h(y-2)&=(2+2(y-2))/(7+(y-2))\\\\&=(2+2y-4)/(7+y-2)\\\\&=(2y-2)/(5+y)\end{aligned}`
