How do you solve and graph #abs(n+2)>=1#?
See a solution process below:
The absolute value function takes any term and transforms it to its non-negative form. Therefore, we must solve the term within the absolute value function for both its negative and positive equivalent.
Subtract Or Or, in interval notation: To graph this we will draw a vertical lines at The lines will be a solid lines because the inequality operators contain an "or equal to" clause. We will shade to the left and right of the lines to show the intervals:

To solve the inequality ( |n + 2| \geq 1 ), you need to consider two cases:
-
When ( n + 2 ) is non-negative: In this case, the absolute value of ( n + 2 ) is just ( n + 2 ), so the inequality becomes ( n + 2 \geq 1 ). Solve for ( n ) to get ( n \geq -1 ).
-
When ( n + 2 ) is negative: In this case, the absolute value of ( n + 2 ) is ( -(n + 2) ), so the inequality becomes ( -(n + 2) \geq 1 ). Solve for ( n ) to get ( n \leq -3 ).
Combining the results from both cases, the solution to the inequality is ( n \leq -3 ) or ( n \geq -1 ).
To graph the solution on a number line, plot an open circle at -1 and shade to the left to represent ( n \geq -1 ), and plot an open circle at -3 and shade to the right to represent ( n \leq -3 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
