I'm not sure how to do this

Step-by-step explanation:

s they want to know what the number of the function is at the number given in the f(x) and g(x)

which for f(-8) is -5

and g(4) is 3        

I'm getting the numbers from the graph

sooo plug the numbers into the expression given

-1 * f(-8) - 4* g(4)

= -1*-5 - 4 * 3

= 5 -12

= -7

Hope that helps :)
