Question

When looking at a rational function f(x)=(x+3)(x-2)(x+5) / (x-3)(x+2)(x-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

Answer 1

Can anyone help with this?

Answer 2

I believe Bobby is correct, because if x= -2, 3, and 5 then the denominator equals zero which means it is undefined.
