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 ...

You can also plot graphs for trigonometric equations (equations that use sine, cosine, and tan, etc.), establish graphs for linear and quadratic ... For example, in the equation y=mx+c, you ...
