Question:

Which of the following best describes the range of $1366_w105_h20.png$?

A y ≤ 7
Explaination

The range of a function describes the set of all outputs, y, that satisfy the equation defining the function. In the xy-plane, the graph of $1366_w105_h20.png$ is a U-shaped graph that opens downward with its vertex at (0, 7). Because the graph opens downward, the vertex indicates that the maximum value of y is 7. Therefore, the range of the function defined by $1366_w105_h20.png$ is the set of y-values less than or equal to 7.
