Answer:

D: (-infinity, infinity) R: (-infinity, infinity)

Explanation:

The absolute value of x - 3 is x+ 3.

y = x + 3 + 1

y = x + 4

Your y intercept is your c value. Your c value is 4.


4 is your y intercept.


Place a point on 4. This is your starting point. Rise over run is 1/1


To find the positive points, go up one from the y intercept and over one, repeating the process until you reach the edge of the graph.


To find the negative points, do the opposite. Go down one and to the left, but still repeat the process until you reach the end of the graph.


Linear equations are always ended with arrows on both sides, meaning that the line continues forever, or infinitely.


To find domain, look at the x values.


Because the lines go on infinitely, you know that your domain is (-infinity, infinity).


To find your range, look at your y values.


Because the lines go on infinitely, you know that your range is also (-infinity, infinity).


Make sure to use the symbol for infinity instead of the words. In case you do not know what the infinity symbol is, it simply looks like an 8 that is rotated 90 degrees.
