Answer: -7
Step-by-step explanation:
First, lets use the functions to find the answer to f(-8) and g(4)
f(-8) is the same as asking for the value of y when x is -8
Therefore, f(-8) = -5 (according to the graph)
Using the same rule, g(4) would be the value of y when x = 4 which,
according to the graph, g(4) = 3
Plug these values back into the original equation to get:
[tex]-1*f(-8)-4*g(4)=?\\=-1*-5-4*3\\[/tex]
using the order of operations, we will multiply the values first
[tex](-1*-5)+(-4*3)\\=5+(-12)\\=5-12\\=-7[/tex]
Therefore, our final answer is -7
