Answer 1

Do you know how a function works?

Answer 2

Not really

Answer 3

So each coordinate is given by an (x,y) notation, for example, (0,1) x=0 and y=1

Answer 4

So for each x, what is happening to the to given the result of the y coordinate?

Answer 5

Let's just try trial and error... lets use y=x^4

Answer 6

So for the first coordinate x=0, if we use y=x^4, we substitute the value for x directly into the function and see what y is!

Answer 7

1 or 0?

Answer 8

So, y=(0)^4 = 1, which corresponds correctly to the first coordinate given! So A could be correct, but if we look at the other function, D could also be correct. Lets check another coordinate.

Answer 9

0^4 is zero

Answer 10

(x,y)=(1,4), subbing into the function y=x^4 = (1)^4 = 1. So in this function y=1 when x=1. So the answer cannot be A.

Answer 11

oops, you are correct @agent0smith, thanks for catching that.

Answer 12

So then its D?
