A. The range of the relation is the single value___
B. The range of the relation is the interval_

Use vertical line test to determine whether the graph is the graph of a function.

Look at the y axis. You can see that the graph reaches a minimum at y=3, and then grows indefinitely.

This implies that the range is . In fact, the range is exactly the set of all values reached by the function's outputs.

The vertical line test states that a graph is a function if and only if every possible vertical line crosses the graph at most once.

You can see that this is the case, so this is the graph of a function indeed.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
