Solve the equation or inequality using analytic methods. Support your answer graphically. Identify any identities or contradictions.

Consider the linear function

(a) Solve the equation f(x) = 0 graphically. Give the solution to the nearest hundredth. Then explain how you went about solving the equation graphically.

(b) Refer to your graph, and give the solution set of f(x) < 0.

(c) Refer to your graph, and give the solution set of f(x) ≥ 0.
