1) From the following python definition what is the result of "foo(5)"?

 def foo(x):
     a = 1 + x
     b = 2.5 * a
     c = b / 2
     return c

a) 5
b) 6
c) 7
d) 7.5

2) Write a definition that computes the polynomial (x^3 + 3 — 2x^-2) and prints "The answer is y units." where y is the value of the evaluated polynomial *without returning a value.
