gtfo @userA113 lol what do you think your doing ?

anonymous · Answer

OOO. How fun. xD Urm, Well you know the a^2+b^2=c^2. All you have to do is plug in the numbers.

sorry mate @eddielikestacos

i still need help lol

In A and D, you  values that are increasing by multiplication. They will end up growing at a faster rate than numbers that are added. So the answer is B and C because they increase at a constant rate. Does that make sense?

Well, When you Graph a Variable with an exponent, it will curve. and obviously you dont want a graph that curves. So A and D is Gone. C is an Absolute value which will give you 2 Graphs, so that is gone. so the only one would be B because if you graph y=x+1, Its a straight line. if any of this made sense xD
