E EXAMPLE 3 Understand Stretches and Compressions Try It!
tj(x) = f(3x)
3. Show that j(x) = is a horizontal
stretch of the graph of f. You can use the table
to help you.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

parallelogram is the   answer
