This is possible only when both a and b are finite. (iii) Open-closed interval : (a, b] = {x : a < x b} ( ] or ] ] (iv) Closed - open interval ... WebThe 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 …

Web★★ Tamang sagot sa tanong: How does the special features of parabola related to the behavior of the opening of the graph? How will it affect the rule or formula that defines the graph? - studystoph.com Web11 de mai. de 2016 · Sorted by: 3. The general equation is. y ′ = m x ′ 2. where y ′ and x ′ are coordinates of a point in a rotated and transalted coordinate system. The good news is that if you're willing to write a point ( x, y) as a vector v = [ x y 1], then the equation of a general parabola is just. v t M v = 0. where M is the matrix.
WebGiven a quadratic function f(x) = ax2 + bx + c, depending on the sign of the x2 coefficient, a, its parabola has either a minimum or a maximum point: if a > 0: it has a maximum point. … WebDetermine the parabola's direction of opening: f(x) = 4(x+2)2−8 f ( x) = 4 ( x + 2) 2 − 8 Step 1: To start, determine what form of a quadratic you are given.
