let f(x)=(-2x)/(x2-x-12). There are two numbers that are not in the domain of f. Give the larger value to 2 decimal places.
This will be undefined whenever ( x^2 - x - 12) = 0
So.....factoring, we have
(x - 4) ( x + 3) = 0
And the function is undefined when x = 4 or x = -3
So.....4 is the larger number not in the domain
