(Fog) = f(g(x))
g(-2)=-2+4=2
f(2)=2^2 +3 = 4+3 =7
        
             
        
        
        
slope  = (y2-y1)/(x2-x1)
       =  (2--1)/(5-1)
       = (2+1)/(4)
        =3/4
The point slope from of a line is 
y-y1 = m(x-x1)
y--1 = 3/4 (x-1)
y+1 = 3/4 (x-1)

Average rate of the function: 3
Step-by-step explanation:
The function in this problem is

The average rate of change of a function over an interval 
 is given by

where
 are the values of the function calculated in 
 respectively
For the function in this problem we have:
, so

, so

So, the average rate of change is
