1. Copy and complete the following tables for the functions indicated.
| a. y = 4x | b. y = 4x + 3 | c. y = 4x +1 | ||||||||||||||||||||||||||||||||||||
|
|
|
2. Use the tables above to sketch each of the three functions on the same set of axes.
Use an x-axis from -2 to +2 and a y-axis from 0 to 16.
3. Sketch the following pairs of functions on the same set of axes.
Mark intercepts and use other key points to produce the correct shape.
a. y = 5x and y = 5x + 2
b. y = 3x and y = -3x
c. y = 2-x and y = 2x − 1
