Graphing a quadratic equation examples
WebIn this section, we will go over common examples of questions involving graphs of quadratic functions and their step-by-step solutions. Example 1. What are the x-intercepts of the graph of the quadratic equation f(x)=x 2-12x+27? Example 1 Solution. An x-intercept is a point where a function crosses the x-axis. These are the points (x1, 0) and ... WebThe simplest Quadratic Equation is: f (x) = x 2 And its graph is simple too: This is the curve f (x) = x2 It is a parabola. Now let us see what happens when we introduce the "a" value: f (x) = ax2 Larger values of a squash the curve inwards Smaller values of a expand it …
