Answer 7

Someone please help me!

Answer 8

for example, when I replace \(x=0\), I get: \(y=x^2=0^2=0\) so the point \((0,0)\) belongs to our parabola. Furthermore, when I replace \(x=2\), I get: \(y=x^2=2^2=4\) so also the point \((2,4)\) belongs to our parabola

Answer 9

ok

Answer 10

which graph? im confused

Answer 11

please, you have to search for the graph, which passes at points \((0,0)\) and \((2,4)\)

Answer 12

the last one? or first...

Answer 13

first graph passes at point \((2,2)\) so it is a wrong graph

Answer 14

is it the last one?

Answer 15

the last graph passes at point \((2,6)\), so also that graph is a wrong graph

Answer 16

its the third one... right?

Answer 17

why is it the third one?

Answer 18

because it passes at 2,4 right? i have no clue on this to be completely honest!

Answer 19

I see that the third one passes at point \((2,8)\), am I right?

Answer 20

Is it the second one? Im sorry that I am guessing this. This is one of the hardest subjects to me. I am usually good at doing this if someone gives me hints but this graph stuff is really hard for me. But, i guess since all of the other ones are not it then it has to be the second one... right?

Answer 21

that's right! It is the second graph :)
