The standard form of the equation of the parabola is y = ax2+ bx + c, When the parabola passes through the point (1,4) then, 4 = a+b+c, when the parabola passes through the point (2,9), then 9 = a(2)2+ b(2) + c = 4a + 2b + c, when the parabola passes through the point (-1,6), then 6 = a b + c, Substitute b = -1 c = 3 in the third equation, Put a =2, b = -1, c = 3 in the standard form of parabola equation. Math is all about solving equations and finding the right answer. Create your account. This is a great app, sometimes it doesn't scan the problem correctly but you just have to double check if it is correct and if it isn't then just rescan, but this app has helped a lot. So we could write this as 2 times, b minus k, y if you factor out a 2 and a y, so that's the left-hand side, so that's that piece right over there. Whereas the directrix is $ y = k p $. We use the equation {eq}y=k-p {/eq} to find the directrix. We can find the x intercept, y intercept, vertex, focus, directrix, axis of symmetry using any parabola equation in the form of y However, the axis of symmetry is parallel to the x-axis, and its equation will be: $ (y k)2 = 4p (x h)$ .
