Find equation of parabola without vertex

WebThe parabola equation can also be represented using the vertex form. The vertex form of the parabola equation is represented by: f(x) = y = a (x-h) 2 +k. Here, (h, k) is the vertex point of the parabola. Similar to the standard form of the parabola equation, the orientation of the parabola in the vertex form is determined by the parameter “a ...

WebFeb 14, 2024 · Plug the x value for your axis of symmetry into either equation for your parabola. The y value will be the y value for your vertex. [10] Example: y = 3x2 - 6x - 45 = 3 (1)2 - 6 (1) - 45 = -48 5 Write down the vertex point. At this point, your last calculated x and y values should give you the coordinates of your vertex. Example: (1, -48) Method 4 WebSep 3, 2024 · Explanation: Because the question specifies a function, we must discard the form that is not a function: x = ay2 +by + c and use only the form: y = ax2 +bx +c [1] Using the point (0,3), we substitute 0 for x and 3 for y into equation [1] and the solve for c: 3 = a(0)2 + b(0) +c c = 3 Substitute 3 for c into equation [1]: y = ax2 +bx +3 [1.1] 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) does marks and spencer ship to the us
