Answer: y=-3m+13
Step-by-step explanation:
y=mx+c
m is the gradient
y=-3x+c
We know one point
-2=3(-5)+c
Solve for c
-2=-15+c
13=c
y=-3m+13
Do 33-8 then divide that by two and you should get your answer
ANSWER

EXPLANATION
The given function is:

and



To find g(f(-1)), we substitute x=-1, to obtain;

We simplify the square in the denominator to get,

We now add the denominator to obtain;
