Exercise 2 Page 225

We have been asked to graph a set of functions on the same screen and compare them. To graph the functions, we press on our calculator and write the equations in the first three rows.

Illustration of the calculator with the equations to be graphed written

Next, by pressing the calculator will plot the equations.

Let's discuss the similarities and differences of the graphs.

Similarities

There are two main similarities:

  1. All graphs are linear functions.
  2. All graphs have a intercept of

Differences

There are two main differences:

  1. All graphs have different slopes.
  2. All graphs have a different intercept.
