Learn how to draw the graphs of y = x, y = x² and y = x³, then try it yourself.
The graph of a function y = f(x) is the pictorial representation of the function, which represents the characteristics of the function in a diagrammatic form. Many aspects of the function can be analysed, interpreted and predicted using the graph of a function. The graph of the function y = f(x) means the set of all ordered pairs (x, f(x)) or (x, y) that satisfy the function.
In this section, we will learn to draw the graphs of the functions y = x, y = x² and y = x³.
In this section, the domain and range of all the functions we have discussed are assumed to be the set of real numbers.
