If you are given the graph of a quadratic function or able to graph it with a calculator, then it is simple to find the maximum or minimum value. Look for the vertex of the parabola and draw a horizontal line to the y-axis to find what the minimum or maximum value is.View...
Solve for when the output of the function will be zero to find the x-intercepts. Example 8: Finding the x-Intercepts of a Parabola Find the x-intercepts of the quadratic function f(x)=2x2+4x−4.f(x)=2x2+4x−4. Solution We begin by solving for when ...
