Let f(x)= 2x-5 and g(x)=-3x^2+7x-5. Find each function value. 

a. f(g(2))     First calculate g(2) = -3*2^2 + 7*2 -5.  Do it on your own.
               Next step substitute the obtained value to f(x) and calculate it.

b. g(f(-1))

c. f(f(-4))

d.g(g(-2))

Do the same (or similar things) for all other cases.
