Question

Fill out the table as we did in class for the following:

Answer 1

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)

 1

 2

 

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.
