show ALL of your work in order to earn full credit.
1. (3 points) Consider the function b(x) = 23 (x + 1) − 2. Without evaluating b(x) at any point or
performing any algebraic manipulations, give the slope of the graph and a point on the graph.
2. (3 points) Find a possible formula for the linear function g(x) if g(2) = −10 and g(10) = 14.
3. (4 points) Let f (t) = 5t − 2. Find the value(s) of t for which f (t) = h(t), if any. How many times do
the graphs of f (t) and h(t) intersect?
(a) h(t) = 2t + 1.
(b) h(t) = f (t − 3).
