Question

When looking at a rational function f of x equals the quantity x minus six times the quantity x plus three times the quantity x plus four all divided by the quantity x plus six times the quantity x minus three times the quantity x minus four , Jamal and Angie have two different thoughts. Jamal says that the function is defined at x = −6, x = 3, and x = 4. Angie says that the function is undefined at those x values. Who is correct? Justify your reasoning.

Answer 1

Answer:undefined

Explanation:

If the function is defined at x = –6, x = 3, and x = 4, then the function has a value.
When you use these three values, division by zero happens.

Therefore the function is not defined at x = –6, x = 3, and x = 4.

so jamie is right because dividing by zero breaks math or is undefined

Answer 2

angie is correct.

plugging in any of those values with get a zero on the bottom, thats bad
