Here is where it gets SUPER DUPER EASY
OpenStudy (anonymous):
YAYA I LOVE SUPER DUPER EASY.
OpenStudy (dani_rose):
Just take all the x intercepts and line them up and if there is a number twice it is NOT a function
OpenStudy (dani_rose):
So for A. it would be -4,-4,2,3 and since there is -4 twice IT IS NOT A FUNCTION
OpenStudy (dani_rose):
What happened to options B and C all you gave me was A and D lol

thank you!!!!!!!!!! <3
OpenStudy (dani_rose):
A. had -4 twice
B. had -2 twice
C. had 3 twice
OpenStudy (anonymous):
Your answer is D. When determining whether or not a graph is a function you do a vertical line test. If you can go up and down from a point on the graph without it hitting another point then it is a function.
