Look for the leftmost and rightmost points of the graph. If the graph extends indefinitely to the left or right, the domain ...

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 ...

The first step is to calculate the derivative of the function, often denoted as f' (x). The derivative represents the rate of ...

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. A quadratic function can be drawn as a parabola on a graph. Find out how to plot the graph in ...
