Answer 1

Let's say x = 0.

If x = 0, then what is the value of y?

Answer 2

0?

Answer 3

to graph this, you need to aknowledge that this is a parabola (2nd degree). it may also help to put it into cannonical form

Answer 4

y = x^2 + 2x - 3

y = (0)^2 + 2(0) - 3 ... replace EVERY x with 0

y = ??

Answer 5

y = -3?

Answer 6

good

Answer 7

so we know that (0,-3) lies on this function

Answer 8

when x = 1, y = ???
