SAT ? of the Day

Read the following SAT test question, then click on a button to select your answer.

The graph of y = ƒ(x) is shown above. If 0 t 5, and if (t, v) is on the graph of ƒ, which of the following must be true?

1. –10 v –5


2. –5 v 0


3. 0 v 5


4. 5 v 10


5. 10 v 15

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