Best ResponseYou've already chosen the best response.0this is a quadratic equation, which makes it a parabola. since a for ax^2 is greater than 0 the parabola opens upward. if b^24ac=0, the curve theres only 1 xintercept, instead of 2 roots

Best ResponseYou've already chosen the best response.0if you remember the y=mx+c equation, c is the yintercept. thats how we know. c is always the constant number
