Help! I will medal and fan!

When looking at a rational function f of x equals the quantity x plus three times the quantity x minus two times the quantity x plus five all divided by the quantity x minus three times the quantity x plus two times the quantity x minus 5, Charles and Bobby have two different thoughts. Charles says that the function is defined at x = –2, x = 3, and x = 5. Bobby says that the function is undefined at those x values. Who is correct? Justify your reasoning.

OpenStudy (denonakavro):

Charles is right because the solutions are the zeroes of the denominators

OpenStudy (ofmiceparade):

Can you jusitfy the reasoning? @denonakavro

OpenStudy (denonakavro):

So (x+2)(x-3)(x-5) will be defined as -2, 3, 5

OpenStudy (denonakavro):

Justification ( I am kinda sure): The following equation will be defined at -2, 3, 5 because those are the zeroes where the denominator will be 0

OpenStudy (ofmiceparade):

How do you know the bottom is zero?
