Answer:
Step-by-step explanation:
Construct a 2-columned table for each function. Arbitrarily choose x values to go into the first column, values between -3 and +3:
Example, for y = 3x + 1:
x y = 3x + 1 (x, y)
--------------------------------
-2 3(-2) + 1 (-2, -5)
0 3(0) + 1 (0, 1)

x is the "independent variable." You choose the values, subject to the requirement that -3 < x < +3. The function will return the y values, which are dependent upon the inputs x. This will give you a good number (e. g., 5) points to plot. Draw a line through these points to obtain a graph of
y = 3x + 1. And so on. You need to go through this procedure once for each of the 3 given functions.
