The cost of video taping a basketball tournament is modeled by the function f(x) = 20x + 350, where x represents the cost of each video. What is the rate of change for this scenario? Be sure to put labels on your rate.

The graph of the function f(x) = (x + 2)(x + 6) is shown below. which statement about the function is true? the function is positive for all real values of x where x > –4. the function is negative for all real values of x where –6 < x < –2. the function is positive for all real values of x where x < –6 or x > –3. the function is negative for all real values of x where x < –2.
