Answer:

            h(6) = -27

Step-by-step explanation:

You have three different function, but you task aplies only to h(x)

It looks like you have to find x for which h(x) = -27

h(x) = -3x - 9

- 27 = -3x - 9

 +3x       + 3x

- 27 + 3x  = -9

   +27         +27

   3x  =  18

   ÷3      ÷3

     x  =  6    

check:

h(6) = -3(6) - 9 = -18 - 9 = -27

h(6)=-27 is the answer!
