Given the function h(x)=x+5, what is h(0), h(-2), h(-19), h(9) and h(b+7)

### 2 Answers | Add Yours

You must substitute x by the value which is specified in the brackets.

1) h(0)=0+5=5

2) h(-2)=-2+5=3

3) h(-19)=-19+5=-14 (the sign belongs to the bigger number)

4) h(9)=9+5=14

5) h(b+7)=(b+7)+5=b+12
