First, factor the equation: y = (x + 2)(x + 3) Next, solve for the first set of parentheses: if x + 2 = 0, then x = -2 Solve for the second set of parentheses: if x + 3 = 0, then x = -3 The two x-intercepts for the quadratic function are (-2, 0) and (-3, ...
It may also be the case that the graph of a parabola intercepts the x-axis on one point or doesn't intercept it. How to find the y-intercept in a parabola? A quadratic equation of the form y = ax^2 + bx + c intercepts the y-axis at (0, c). To verify this, simply plug x...
Parabola equations can also be referred to as quadratic functions. One form of this equation is as follows:{eq}y = a(x-p)(x-q) {/eq}In this equation {eq}p {/eq} and {eq}q {/eq} are the {eq}x {/eq}-intercepts, and {eq}a {/eq} is some coeffi...

Intercepts of a Quadratic Function:The intercepts are the points with find on the axes of the Cartesian plane. That is, they are the points where the graph of a function intersects the axes of the Cartesian plane. The {eq}x {/eq}-intercepts of a quadratic function are found b...
How to Find Intercepts in Calculus: Quadratic Formula Example Find the intercepts of the equation y = x2– 2x – 1. Step 1:Set x to 0in your function to find the x-intercept: 02– 2(0) -1 = -1. Written as an ordered pair, the x-intercept is (0, -1). ...
Since your are given the x-intercepts and the y intercept you can use this information to find a Using the factored from of the quadratic equation y = a(x - p)(x - q) where p and q are the x intercpts p = 1/5 =0.2 q = -3 y = a(x - 0.2)(x + 3) Use the given ...
