Question

How do you find discontinuities of rational functions y=x+3(x−4)(x+3)?

Answer 1

Answer:

Step-by-step explanation:

but y = x + 3(x - 4)(x + 3) is a polynomial function and not a rational one.

if you mean y = x / 3(x - 4)(x + 3), then the discontinuities are obtained where the function is not det inre, that is, at x = - 3 and x= 4.
