Question

The profit earned by a sporting goods outlet is modeled in the graph below, where x is the number of years since the outlet opened. He recorded the profit for the first 10 years since the outlet opened.​

Answer 1

Explanation:

Vertex of the given parabola is (4, 160)

Since, graph of the parabola is increasing between x = 0 to x = 4,

Profit earned will be between t = 0 and t = 4

Therefore, domain represents the number of years.

Since, profit of the outlet (y-values) vary from x = 0 to x = 10

And value of profit varies from 0 to 160 thousand dollars, so the range of the function will be (0, 160)

Range of the function represents the outlet's profit.
