Final answer:
To sketch the graph of a function, choose values for x and find the corresponding y-values to plot the points on the graph. Connect the points with a line to represent the graph of the function.
Step-by-step explanation:
To sketch the graph of a function, we need to plot points on a coordinate plane.
Since we don't have specific values to plot, we can still sketch a general graph based on the given information.
If the function is y = f(x), we can start by choosing some values for x and finding the corresponding y-values to plot the points on the graph.
For example, we can choose x = -3, -2, -1, 0, 1, 2, 3 and find the corresponding y-values based on the function given. Once we have enough points, we can connect them with a line to represent the graph of the function.
