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

In this discussion, you are assigned two rational expressions to work  on. Remember to factor all polynomials completely. Read the following  instructions in order and view the example to complete this discussion. Please complete the following problems according to your assigned number.

My assigned number is 32

Question 1

9b2 + 3
41

Question 2

2x – 6
10×2 + 5x

• 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.
• Domain
• Excluded value
• Set
• Factor
• Real numbers
