WebFind the equation of the parabola that passes through the point (2, -1), has its vertex at (-7, 5), and opens to the right. 1 How to convert this parametric parabola to general conic form? WebApr 1, 2024 · Use the formula − b 2a for the x coordinate and then plug it in to find the y. Explanation: A quadratic equation is written as ax2 + bx +c in its standard form. And the vertex can be found by using the formula − b 2a. For example, let's suppose our problem is to find out vertex (x,y) of the quadratic equation x2 +2x − 3 .

WebFeb 13, 2024 · Step-by-Step Guide to Finding the Focus, Vertex, and Directrix of a Parabola. The standard form of Parabola when it opens up or down is (x−h)2 = 4p(y−k) ( x − h) 2 = 4 p ( y − k), where the focus is h,k+ p h, k + p and the directrix is y = k− p y = k − p. The standard form of Parabola when it opens right or left is (y+k)2 = 4p(x−h ... WebWhile the standard quadratic form is a x 2 + b x + c = y, the vertex form of a quadratic equation is y = a ( x − h) 2 + k. In both forms, y is the y -coordinate, x is the x -coordinate, and a is the constant that tells you … Weby = a (x-h)^2 + k is the vertex form equation. Now expand the square and simplify. You should get y = a (x^2 -2hx + h^2) + k. Multiply by the coefficient of a and get y = ax^2 -2ahx +ah^2 + k. This is standard form of a quadratic equation, with the normal a, b and c in ax^2 + bx + c equaling a, -2ah and ah^2 + k, respectively. 1 comment ( 20 votes) party bread and pastries
