Notice how x=-10 is less than x=-7. So we'll evaluate x=-10 using the equation -4x-20

-4(-10)-20=40-20=20


So h(-10)=20

-----------------------

Notice how x=-1 is between x=-7 and x=1. So we'll evaluate x=-1 using the equation 1

Since there are no "x" values here, this means that

So h(-1)=1

---------------------

I'll let you finish the rest.
