Question

Graph the function for the given domain 3x-y = 1; D: {-3, -1, 0, 4}

Answer 1

See in the attached file

Explanation:

In this case, we have the following linear function written in Standard form:

$3x-y = 1$

But we can write it in slope intercept form:

$3x-y = 1 \\ \\ \\ Add \ -3x \ to \ both \ sides: \\ \\ 3x-y-3x = 1-3x \\ \\ -y=-3x+1 \\ \\ \\ Multiply \ by \ -1: \\ \\ y=3x-1$

For the domain D: {-3, -1, 0, 4}, that is, x takes these values, we have the following y-values:

$x=-3 \\ \\ y=3(-3)-1=-10 \\ \\ \\ x=-1 \\ \\ y=3(-1)-1=-4 \\ \\ \\ x=0 \\ \\ y=3(0)-1=-1 \\ \\ \\ x=4 \\ \\ y=3(4)-1=11$

By using graphing tools we can graph the points:

$(-3,-10) \\ \\ (-1,-4) \\ \\ (0,-1) \\ \\ (4,11)$

The graph is shown below.
