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

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

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.

answer: 3.26019516

step-by-step explanation:

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
