Solution Steps

Step 1: Solve f(x) = 10

From the graph, we see that f(x) = 10 at x = 20.

Step 2: Solve f(x) = 15

From the graph, we see that f(x) = 15 at x = 40.

Step 3: Solve f(x) = 0

From the graph, we see that f(x) = 0 at x = -20.

Final Answer

  1. For what value of x does f(x) = 10?
    • x = 20
  2. For what value of x does f(x) = 15?
    • x = 40
  3. For what value of x does f(x) = 0?
    • x = -20
