OpenStudy (dani_rose):

Dude this is my specialty

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

good :)

OpenStudy (dani_rose):

Ok so i'll start with A.

OpenStudy (anonymous):

alrighty

OpenStudy (dani_rose):

The points on A. are (-4,0),(-4,4),(2,-1), and (3,4)

OpenStudy (dani_rose):

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

OpenStudy (anonymous):

i gave em all lol they're up there

OpenStudy (dani_rose):

my bad lol

OpenStudy (dani_rose):

Now onto B

OpenStudy (anonymous):

C is right above D

OpenStudy (dani_rose):

I can tell you that the answer is D since in all the other ones it has a number twice

OpenStudy (anonymous):

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.

OpenStudy (dani_rose):

Your welcome <3

OpenStudy (anonymous):

Well, school is about to be over so i have to go! ill probably need help tommoro if your on

OpenStudy (dani_rose):

ok lol i'll be here
