Steps to graph a parabola
網頁A parabola is not 1:1, because two x inputs can yield the same output. For example: y = x² , both -2 and 2 give y = 4. So if you were to invert this, the horizontal parabola cannot be a function; it wouldn't pass the VLT, because when x = 4, y = 2 and-2. 網頁y = 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.

網頁2024年3月21日 · Follow the below steps to sketch the graph of the parabola y = y = 2 ( x + 3) 2 − 2. Step 1: Determine the vertex by comparing the given parabola with vertex form of the parabola equation, which is y = a ( x − h) 2 + k where ( h, k) is the vertex point of the parabola. We have y = 2 ( x + 3) 2 − 2 ⇒ y = 2 ( x − ( − 3)) 2 + ( − 2) 網頁In solving quadratic INequalities Sal shows how you can solve for f (x) > 0 or f (x) < 0. Meaning the x coordinates at which point the f (x) line is above (>) or below (<) the x-axis (0). The two are related because the points where the f (x) line intersect the x-axis (=0) are also the same points between which the f (x) line rises above (>) or ...

網頁2016年3月27日 · Because a = 2, the focal distance for this parabola is 1/8. With this distance, you can write the focus as the point ( h, v + 1/4 a ), or (1,–2-7/8) Third, find the directrix. You can use the equation of the directrix: y = v – 1/4 a, or y = –3-1/8. Last, graph the parabola and label all its parts as shown.
