WebFeb 23, 2024 · In function notation, the solutions of f (x) = 0 (note the similarity to y = 0) are the x-coordinates of the points where the graph of f crosses the x-axis. Analyzing the graph of f in Figure 3.15.3.1, we see that both −3 and 2 are solutions of f (x) = 0. Thus, the process for finding the x-intercepts is clear. WebSince these points occur where y = 0, the zeros of a quadratic function occur where f(x) = 0, or at the x-values that make {eq}ax^2 + bx + c =0 {/eq} a true equation.
