Final answer:
To solve for x when h(x)=0 in the given equation h(x)=-x-1, substitute h(x) with 0 and solve for x.
Step-by-step explanation:
To solve for x when h(x)=0, we can use the given function h(x)=-x-1. Substitute h(x) with 0 and solve for x:
0=-x-1
Now, let's isolate x by adding 1 to both sides:
1=-x
Finally, multiply both sides by -1 to solve for x:
x=-1
Therefore, the value of x when h(x)=0 is x=-1.
