Answer:
standard form for a quadratic expression
Step-by-step explanation:
This is a quadratic expression. If you want this expression in standard form, write the terms in descending order of powers of x: -2x^2 + 1.
This -2x^2 + 1 has not yet been factored.

Step-by-step explanation:
The sketches are illustrations of inequalities
- <em>The first sketch is: </em>

<u />
<u>Sketch A</u>
In sketch A, we have the following observations:
- <em>The arrow faces left (this implies less than)</em>
- <em>The dots on -2 and -5 are closed dots (this implies less than or equal to).</em>
<em />
Hence, the inequality is:

<u />
<u>Sketch B</u>
In sketch B, we have the following observations:
- <em>The arrow faces right (this implies greater than)</em>
- <em>The dots on -4 and 3 are closed dots (this implies greater than or equal to).</em>
<em />
Hence, the inequality is:
