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.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
