WebNov 10, 2015 · To find a, plug in the values from either known point (x-intercepts). I'll use (1,0): You can convert it to standard form (y = ax 2 +bx+c) by multiplying out the (x-3) 2 … WebUse the general equation $y=a(x-h)^2+k$, where $(h,k)$ are the coordinates of the vertex. You already know that the $y$-coordinate of the vertex is $k=-7$.
WebOct 25, 2014 · Since the equation for a parabola describe a quadratic function. y = ax2 +bx +c, where a, b, and c are any real numbers such that a ≠ 0, we can find the x-intercepts by solving the quadratic equation. ax2 + bx + c = 0. One way to do that, we can use the quadratic formula. x = −b ± √b2 −4ac 2a. I hope that this was helpful.
