In this instance, x=0. Do the same for x=1, x=2, x=3 and x=4. Image caption, STEP 3 - Draw a graph and label the x axis 1 to 4 and the y axis 1 to 9. A linear equation is represented as a line graph.

Therefore, aim to recognise the equations and graphs of quadratics, cubics, reciprocals, exponentials and circles. Sketch \(y = x^2 + x − 6\). The quadratic factorises to give \((x + 3)(x − 2 ...
