Consider a quadratic equation: y = x² − 2x − 3. Now, the graph of this quadratic equation will be in the shape of a parabola. We assume it to have a “U” shape in which it would either open up or down. In order to solve for the x-intercept of this problem, we ...
WebIn order to find the x-intercept, we will make the y coordinates of the curve 0 because the x-intercept is the point where the curve cuts the x-axis and at the x-axis, the coordinate of y is equal to 0. Hence, keeping y = 0 , we get ax 2 + bx + c = 0. We have to solve the quadratic equation to find the intercepts on the x-axis. WebThis video explains how to find the x and y intercepts of a quadratic function. The x-intercepts require the use of the quadratic formula.Site: http://mathi...
WebOct 6, 2024 · To do this, set y = 0 and solve for x. x + 3 = 0 or x − 1 = 0 x = − 3 x = 1. Here when y = 0, we obtain two solutions. There are two x -intercepts, (−3, 0) and (1, 0). Step 3: Determine the vertex. One way to do this is to use the equation for the line of symmetry, x = − b 2a, to find the x -value of the vertex.
