1. Evaluate the following sums:
a.
b. (a is a constant)
c.
d.
(Evaluate d using the "formulas" for summing integers and squares of integers. Hint: Look at sheet with induction problems.)
2. Given: Let g(x) =
and f(x) = 
compute:a. f(-3.2) b. g(-3.2) c. f(3.4) d. g(3.5) e. f(3/4) f. g(f-2.1) =
3. Graph g(x) and fx).
