Best ResponseYou've already chosen the best response.0To find the x intercept of the parabola, you have to set a parabola equation. Use standard form equation to fillin the vertex information from your given point, (h, k). \[y=a(xh)^2+k\] Plug in the given point in the graph. Once you've done that, substitute the yintercept coordinate values into the equation and solve for a. After finding a, just plug in (h, k) and a into the standard form equation. Also, to find the xintercept, just set y = 0 and solve for x from the standard form equation.
