How to Graph a Function in Excel. A mathematical function is a formula that takes an input, x, applies a set of calculations to it, and produces an output called y. By calculating a function at a ...

Graphs of quadratic functions can be used to solve equations. Example. Draw the graph of \(y = 2x^{2} + 2x – 4\) for values of –3 to 2. Use the graph to solve the equation \ ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c\) is a smooth curve with one turning point. The turning ...
