Angie is right.

if x = -6 what do you think the value of the denominator is?

(-6 + 6)(x - 3)(x - 4) = 0(x + 3)(x - 4)

Any of the 3 values subbed in will give you a divide by 0 situation.

do you follow that @CUTIEPIEI37/

umm kind of

if we any of the factors are 0 it will make the whole demnominator = 0

oh ok so then the whole function is zero

if x = -3
then we have (x + 6) * 0 * (x + 4) = 0

Anything divide by zero is undefined.

- or undefined

oh ok

Using limit on it doesn't work either cause it diverges.

it wil still be undefined

*will

yep

thank you you guys thank you so much i think i might be able to explain it thank you

yw

@iwanttogotostanford hope this helps :))

I chose it because it made (x +6) equal to zero
