Examples of equations that form quadratic graphs ... 2x – 4\) for values of –3 to 2. Use the graph to solve the equation \(y = 2x^{2} + 2x – 4\). Let's use the graph from the previous ...

All quadratic functions have the same ... x-coordinates of the points where the graph crosses the x-axis. Draw the graph of \(y = x^2 -x – 4 \) and use it to find the roots of the equation ...
