Find the domain of the rational function below. F(x)= (x-4)(x+2)/(x+3)(x-4)

{x ≠ -3 ∪ x ± 4}

Step-by-step explanation:

The (x - 4) terms cancel, but x still may not = 4 (which would cause division by zero).  Also, (x + 3) may not be zero (for the same reason), and so x ≠ -3.

The domain of this function is {x ≠ -3 ∪ x ± 4}

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
