The graph of y = function f of x is shown above. If 0 less than or equal to t less than or equal to 5, and if (t comma v) is on the graph of function f, which of the following must be true?

Answer Choices

Right-o!

Explanation

The second coordinate of a point on the graph corresponds to v. From the graph, you can see that for 0 less than or equal to t less than or equal to 5, the smallest value of v is 5 and the greatest value is 10, so 5 less than or equal to v less than or equal to 10.
