# Number 2

Domains of Rational ExpressionsIn 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. (Instructors will assign each student their number.)If your assigned number is:Your first rational expression isYour second rational expression is1a2 + 2a 1011a2x 8×2 x2y2 + 11y + 30y + 55a 3a2 493u2 + u 723u 152w 1w2 94×2 6x 55×2 3x 28b 34b2 16516b2 12b2 + 11b 6c2 + 2c 1010c2 80c + 16064w2 95wy2 42y2 + y 17a2 + 6a + 9a 10t2 + 2t 10t2 6t + 8881m2 165m + 1022x + 112×2 x93a2 + 16a + 5a2 7a + 10b2 + 7b + 10b2 9104×2 16x 18r2 + 2r 24r 211t2 14t + 494t 83q2 22q + 24q2 112v2 v 20v2 + 4v + 36t 3t13n2 2n 15n 28k + 68k2 + 2k 31464k2 92s2 + 2s 15s2 36154k2 12k + 94k3w2 + 362w 8165m2 + mm + 612a 155a 25177t2 14t4t2 936 w2w1822x + 11×2 3x 101 2c20c2 + 10c1920c3 + 5c2 c7c 143a2 12a24a2 18a20g2 366g2 + 15g7n 24n2 25211 2x + x2x2 12c2 + 5c 2514c 2122144 w28 2wz2 8z + 1612234 + 16n2n 83×2 2x 1×2 8124y2 256y372p 4p225a2 100a2 + 5a + 63b2 9b 8261 x2x2 + 10x + 252u 21 u273z + 33z5y3 75y2y2 + y 15289 36x2815k2 5kk2 k 3029×2 7x + 125xw2 9w 3616w2 130m2 + 13m + 406m4y 325y2 431k2 8k172b + 13b2 12329b2 + 3412x 610×2 + 5x3315x2 + 4550x42m2 3m34g2 + 46gg3k + 1k2 + k 42354a 5144m3 +16m3m2 m36x2 2523b2 18b + 813b2 12379m2 4235x + 15×2 4938d2 + 933m2 + 4m 55m2 + m3913n2 13n6n2w + 19w2 1404×3 16x142b2 841×2 + 2x 103x2x 8×2 7x + 1042×2 + x 72245b 3b2 443w2 + 11w + 307w2n 14n2 944g2 6g 55gk3 + kk2 k 424516t2 164×2 + 2x 103x 15Explain 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.DomainExcluded valueSetFactorReal numbersYour 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.
