Inequalities are used to show the relationship between unequal expressions
- <em>The set notation of (5) and (6) are: </em>
<em> and </em>
<em>.</em> - <em>See attachmen</em>t for the graphs
The following should be notated when plotting the graph of an inequality
- < and > are represented with open circles, while
and 
are represented with closed circles - The arrows of
and 
point to the left, while the arrows of 
and point to the right.
So, we have:
Rewrite as:
The graph of will point to the right, and it will use an open circle
Split the inequality:
and 
<em>It is not possible for -6 to be less than x and at the same time, x is greater than or equal to -2.</em>
<em />
Hence. 
cannot be represented on a graph
Split the inequality:
and 
means that -4 is less than x or x is greater than -4.
So, we have:
and
If and , then we make use of because it contains more values of x.
The graph of will point to the right, and it will use an open circle

Negative, You'll have to explain the why part though,
The x intercept occurs when y = 0.
0=(x+2)^2 - 1
1=(x+2)^2
Take the square root of both sides. Note that the sqrt of 1 is 1. Then solve for x.
1=x+2
-1=x
The x intercept is -1.
The y intercept occurs when x=0.
y=(0+2)^2 - 1
y=2^2 -1
y=4-1
y=3
The y intercept is 3.
Now, to find the vertex...
This parabola is currently in a format called the vertex form, which is:
f(x) = (x-h)^2 + k
where (h, k) is the vertex.
Therefore, the vertex is (-2, -1).
