Final answer:
To draw the graph of y = 3sin(2x) - cos(x), label and scale the axes appropriately. Plot points by substituting different x values into the equation and connect them to form the graph.
Step-by-step explanation:
To draw the graph of the equation y = 3sin(2x) - cos(x), we need to label and scale the x and y axes appropriately. Based on the given information, we will use a scale of 2cm to 30cm for the x-axis and 2cm to 1 unit for the y-axis. The x-axis should be labeled as the angle 'x' in degrees or radians, and the y-axis should be labeled as 'y' in units.
Next, we can plot the points on the graph by substituting different values of 'x' into the equation to find the corresponding 'y' values. For example, if we substitute x = 0 into the equation, we get y = 3sin(0) - cos(0) = 0 - 1 = -1. So, the point (0, -1) should be plotted on the graph.
By repeating this process for different values of 'x', we can plot multiple points and then connect them to form the graph of the equation.
