Discussion 1: Domains of Rational Expressions
Factor all polynomials completely, use my first letter of my name which is Latoya.
The first rational expression is x^2 – 25 over 2
The second rational expression is 37 over K^2 – K – 30
. 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.
. 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.
Domain
Excluded value
Set
Factor
Real numbers
No plagiarism, do not use any definition for the words.
