Let f(x)=x^2 and g(x)=x-5 find:
a. (f o g)(x)= f[g(x)] = f(x-5) = (x-5)^2
-----------------------------------------------
b. (g o f)(x)= g[f(x)] = g[x^2] = x^2-5
-------------------------------------------
c. (f o g)(-3) = f[g(-3)] = f[-8] = 64
---------------------
d. (g o f)(-3)= g[f(-3)] = g[9] = 4
-----------
