Ashford 2: - Week 1...

Ashford 2: - Week 1 - Discussion 1

Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses.

Domains of Rational Expressions

In this discussion, you are assigned two rational expressions with which you will work. Remember that each polynomial must be fully factored and that you can only cancel factors; you cannot cancel terms. Read the following instructions in order and view the example to complete this discussion:

• Find your two rational expressions in the list below based on the first letter of your first name.

X2-36

36

7w-2

16w2-1

• Explain in your own words what the meaning of domain is. Also, explain why a denominator cannot be zero.

• Find the domain for each of your two rational expressions.

• Write the domain of each rational expression in set notation (as demonstrated in the example).

• Do both of your rational expressions have excluded values in their domains? If yes, explain why they are to be excluded from the domains. If no, explain why no exclusions are necessary.

• Incorporate the following five math vocabulary words into your discussion. Use bold font to emphasize the words in your writing (Do not write definitions for the words; use them appropriately in sentences describing your math work.):

o Domain

o Excluded value

o Set

o Factor

o Real numbers

Your initial post should be at least 250 words in length. Support your claims with examples from required material(s) and/or other scholarly resources, and properly cite any references. Respond to at least two of your classmates’ posts by Day 7. Is their work for similar to your own? Did they factor and cancel correctly? Are their answers in lowest terms?

Carefully review the Grading Rubric for the criteria that will be used to evaluate your discussion.
