Question

Does this graph represent a function? Why or why not?

-10 8042
A. Yes, because it passes the vertical line test.
OB. No, because it fails the vertical line test.
C. Yes, because it passes the horizontal line test.
D. No, because it is not a straight line.

Answer 1

The given graph only shows one point, which is (-10, 8042). A single point cannot be used to determine whether the graph represents a function or not. We need at least two or more points to determine whether a graph represents a function or not. Therefore, we cannot conclude whether this graph represents a function or not based on the given information.In order to determine whether a graph represents a function or not, we can use the vertical line test. If any vertical line passes through the graph at more than one point, then the graph does not represent a function. Conversely, if every vertical line passes through the graph at most one point, then the graph represents a function.
