Question

Use the vertical line test to determine whether the relation is a function. If not, identify two points a vertical line would pass through.

Answer 1

A vertical line test is a graphical approach for assessing if a curve in the plane reflects the graph of a function. The correct option is C, function.

What is a Vertical-line test?

A vertical line test is a graphical approach for assessing if a curve in the plane reflects the graph of a function by visually inspecting the curve's intersections with vertical lines.

Since the graph of the given function, intersect the vertical axis or the y-axis at most one time, therefore, the given graph passes the vertical line test. Thus, it can be concluded that the given graph is a function.

Hence, the correct option is C, function.
