Finding y intercept in quadratic function
WebOct 26, 2024 · The graph of a quadratic function is a parabola. A parabola can cross the x-axis once, twice, or never. These points of intersection are called x-intercepts. Before tackling the subject of the x-intercept, students should be able to confidently plot ordered pairs on a Cartesian Plane. X-intercepts are also called zeros, roots, solutions, or ... WebMuch as we did in the application problems above, we also need to find intercepts of quadratic equations for graphing parabolas. Recall that we find the [latex]y[/latex]-intercept of a quadratic by evaluating the function at an input of zero, and we find the [latex]x[/latex]-intercepts at locations where the output is zero.Notice that the number of …
