Solutions

Chapter 1.8, Problem 29E
To determine

To graph: The region provided by the set {(x,y)||x|>4} .

Expert Solution

Explanation of Solution

Given information:

The set, {(x,y)||x|>4} .

Graph:

The graph of the region provided by the set {(x,y)||x|>4} is sketched in the coordinate plane.

Recall that |x|>a is equivalent to x>a or x<a .

Therefore, |x|>4 is equivalent to x>4 or x<4 .

Construct broken vertical lines x=4 and x=4 and shaded the region outside it.

The region obtained is provided below,

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 1.8, Problem 29E

Interpretation:

The region provided by the set {(x,y)||x|>4} is shaded region. The broken vertical line at x=4 and x=4 denote that they are not included in the region.The region consists of all those points whose x-coordinate does not lie between x=4 and x=4 . Therefore, shaded region is the region outside broken vertical lines x=4 and x=4 and these two vertical lines are not included in the region.
