Question

Which of the following does not represent a function?

graph of positive parabola oriented about the y axis with y intercept at negative 6

graph of a line with negative slope through the origin

graph of an absolute value function

graph of a parabola symmetric about the x axis with x intercept at negative 5

Answer 1

D I JUST TOOK THE TEST!!!!!!!! :)

Answer 2

graph of a parabola symmetric about the x axis with x intercept at negative 5

Step-by-step explanation:

A parabola that opens horizontally does not pass the vertical line test. You can draw a verticla line that intersects the curve in 2 places. A function must be single-valued, so can only have one y-value for any x-value.
