Question

1. function tables:

use the function: $y = 2x - 7$ to fill in the function table.
then graph the function.

x	-1	0	1	2
y

Explanation:

Step1: Substitute x = -1 into y = 2x - 7

$y = 2\times(-1) - 7 = -2 - 7 = -9$

Step2: Substitute x = 0 into y = 2x - 7

$y = 2\times0 - 7 = 0 - 7 = -7$

Step3: Substitute x = 1 into y = 2x - 7

$y = 2\times1 - 7 = 2 - 7 = -5$

Step4: Substitute x = 2 into y = 2x - 7

$y = 2\times2 - 7 = 4 - 7 = -3$

Answer:

The completed function table is:

x	-1	0	1	2

To graph the function $y = 2x - 7$, plot the points $(-1, -9)$, $(0, -7)$, $(1, -5)$, $(2, -3)$ on the coordinate plane and draw a straight line through them (since it is a linear function).
