WebSolution: The directrix of parabola is x + 5 = 0. The focus of the parabola is (a, 0) = (5, 0). For the parabola having the x-axis as the axis and the origin as the vertex, the equation of the parabola is y 2 = 4ax. Hence the equation of the parabola is y 2 = 4 (5)x, or y 2 = 20x. Therefore, the equation of the parabola is y 2 = 20x.

WebThe parabola opens "sideways" and the axis of symmetry of the parabola is horizontal. The standard form of equation of a horizontal parabola is x = ay2 + by + c where a , b , and c are all real numbers and a ≠ 0 and the equation of the axis of symmetry is y = − b 2a . Compare the equation with x = ay2 + by + c to find the values of a , b , and c . WebApr 29, 2016 · Solution: Let’s make sure it is a parabola by checking its determinant: 24 2 − 4 ( 16) ( 9) = 576 − 576 = 0. The determinant is 0, so it is a parabola. First, we find the rotation angle because the sign depends on the rotation angle. The angle of rotation is θ = 1 2 cot − 1 ( 16 − 9 24) = 1 2 cot − 1 7 24 ≈ 36.89 ∘. WebThe vertex of this parabola is at (h, k). The focus is at (h, k + p). The directrix is the line y = k - p. The axis is the line x = h.
