Question

How do I graph y=x^2 + c when c is -2

Answer 1

Do you know what the base graph looks like, y=x^2?

Answer 2

y=ax^2+bx+c

Answer 3

It wants to know what the affect of c is when c is -2,-1,0,1,2 or as it increases

Answer 4

Ok, you know y=x^2 is a parabola with vertex at the origin, the c value will shift the graph up or down depending on if its negative or positive

Answer 5

So the c is what moves it on the y axis?

Answer 6

Yes it shifts it up or down c units. So if it was -2 it would shift the graph down 2 units

Answer 7

Oh ok I see.. Thank you!

Answer 8

So does that mean that the b value determines there placement on the x value?

Answer 9

What's the b value?

Answer 10

they give me the same equation but different values for the b (-2 -1 0 1 2 ) to compare with the c value

Answer 11

Where is the b value in the equation? For the first one you had an example where c was y=x^2+c

Answer 12

y=ax^2 + bx + c

Answer 13

Im actually not sure about that one...=p
