Find
(f o g)(x)
(g o f)(x)
if they exist

f%28x%29+=+2x+%2B+7
g%28x%29+=+-5x-1


(f o g)(x) =f%28g%28x%29%29
(f o g)(x) =f%28-5x-1%29
(f o g)(x) =2%28-5x-1%29%2B7
(f o g)(x) =-10x-2%2B7
(f o g)(x) =-10x%2B5


(g o f)(x) =g%28f%28x%29%29
(g o f)(x) =g%282x+%2B+7%29
(g o f)(x) =-5%282x+%2B+7%29-1
(g o f)(x) =-10x+-35-1
(g o f)(x) =-10x+-36
