First, notice where each of these lines crosses the x negative axis.Mar 29, 2022 · The method for finding the \(y\)-intercept of a quadratic function or the \(y\)-intercept of a parabola is the same as that of a line. If a quadratic equation is given, substitute \(x = 0\) and solve for \(y\) to get the \(y\) intercept. Finding the \(y\)-Intercept – Example 1: Find the \(y\)-intercept of the equation \(y=x^2-2x-3\). Solution: This tells you that the y-intercept is 3. Since any point along the y-axis has an x-coordinate of 0, the form of any y-intercept is \((0, c)\) for some number \(c\). Using algebra to find the y-intercept of a function. To find the y-intercept of a function, let \(x = 0\) and solve for \(y\). Consider the following example. Example | Cifmuq (article) | Mwknk.
