Question

Which of the following does not represent a function? (1 point) graph of an absolute value function graph of a negative parabola oriented about the y axis with y intercept at positive 6 graph of an ellipse with y intercepts negative 7 and positive 7 graph of a line with a positive slope and y intercept of negative 6

Answer 1

The ellipse

Step-by-step explanation:

An ellipse can never be a function.

Answer 2

The graph of an ellipse with y intercepts negative 7 and positive 7 is not a function. The definition of a function requires that every element of the domain corresponds to exactly one element of the range. However, every x value of an ellipse has two values of y (if you draw a vertical line at certain x value, the line will intercept the ellipse twice.)
