Question

Does this graph represent a function

A. No, because it fails the vertical line test.
B. Yes, because it is a curved line.
C. No, because it is not a straight line.
D. Yes, because it passes the vertical line test.

Answer 1

no,because it falls the vertical line test

Answer 2

Explanation:

The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.
