Question

discontinuities of f[x]=[x^2-36]/[4x+24]

Answer 1

What does x equal when the denominator is zero? That will be where the function is discontinuous b/c division by zero is undefined.

Answer 2

x ≠ – 6
!! right?

Answer 3

yup!

Answer 4

yayy!

Answer 5

woohoo!

Answer 6

And if you have a 2nd degree polynomial like (x+2)(x+1) that isn't factored this way, then make sure to factor it and find what x will equal when the denominator is zero.

Answer 7

tat makes sense.
