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 \ ...

Solving quadratic equations - Eduqas Graphs of quadratic functions. ... Example. Draw the graph of \(y = x^2 -x - 4 \) and use it to find the roots of the equation to 1 decimal place.

Features of linear graphs. Linear graphs are straight-line graphs that visually represent a constant rate of change in the relationship between two variables, showing how one changes in response to ...

Linear functions, graphs and equations. Linear functions are fundamental building blocks in mathematics and play a key role in solving real-world problems where the rate of change remains constant.
