WebbIn algebra, a cubic equation in one variable is an equation of the form + + + = in which a is nonzero.. The solutions of this equation are called roots of the cubic function defined by the left-hand side of the equation. If all of the coefficients a, b, c, and d of the cubic equation are real numbers, then it has at least one real root (this is true for all odd … Webb29 jan. 2024 · You are right - since the vertex is above the focus, the parabola must open downwards. So p = − 10 and the parabola has equation ( x − 1) 2 = − 40 ( y − 2). Note that the right hand side is never negative because for all points on the parabola y ≤ 2 (because the parabola opens downwards).

WebbAnswer (1 of 4): How do I represent the graph of the parabola y^2=4x? Good morning Catalina. You have asked a great question and one which gives a good insight into an understanding of Parabolas. Let's go back to some basics first. The General Equation for a Parabola is Y = AX² + BX + C wher... WebbNot all parabolas are congruent to the basic parabola. For example, the arms of the parabola $y=3x^2$ are steeper than those of the basic parabola. The $y$-value of each point on this parabola is three times the $y$-value of the point on the basic parabola with the same $x$-value, as you can see in the following diagram.
