<h3>What is an algebraic expression?</h3>
Algebraic expressions are mathematical expressions. They usually consist of one or more variables with their coefficients and arithmetic operators such as: (division, multiplication, addition, and subtraction).
From the given expression, we are to determine an expression that is equivalent to:

To do this, we are going to simplify the above-given expression to its lowest term since we are not given any options to choose equivalent expressions from.
By doing so, we have:

Answer: neither graph A nor graph B, because, even though both curves are above the horizontal axis, neither graph has an area of 1
Step-by-step explanation:
<em>Areas under the graphs:</em>
<em />
<u>Graph A</u>
<u />
<u>Graph B</u>
<u />
As neither of these graphs have an area of 1, neither of them are density curves.
