Use the graph to find (fg)′(4).
A) -12
B) -16
C) 4

we know that

The intersection point of both graphs is a common point for both functions, for which for the same input value, both functions will have the same output value.

so

the point of intersection is

for an input value equal to

the output value for both functions is

therefore

the answer is the option

X= 4
