Find the x-intercepts of the quadratic function. y=4x2−3x−7 Definition of X-Intercepts: If a function y=f(x) is represented as a quadratic function, then use the following quadratic formula to compute the required x-intercepts by equating the variable y with zero. x=−b±b...
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...
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, ...
The values of the x-intercepts of a quadratic equation must satisfy the quadratic equation as these two points are on the graph of the quadratic equation.Answer and Explanation: A quadratic equation takes the form y=ax2+bx+c. We are given that the quadratic equation ...
