Question 331558: Find all numbers for which the rational expression is undefined. n^3-8n/n^2-49

Answer by nyc_function(2741) (Show Source): You can put this solution on YOUR website!
To find which numbers will create a zero in the denominator (which number will make this rational function undefined), set denominator to zero and solve for n.
n^2 - 49 = 0
n^2 = 49
sqrt[n^2] = sqrt[49]
n = -7 and n = 7
The numbers that will make this function undefined are n = -7 and n = 7.
