domain of f(x)=(x^2-3x-4)/(x-4)

domain

f (x) = \frac{x ^{2} - 3 x - 4}{x - 4}

x < 4 or x > 4

Solution steps

Find undefined (singularity) points:

x = 4

The function domain

x < 4 or x > 4

x^{3} + 2 x^{2} - x - 2

f (x) = x^{2} - 49

(\frac{1}{x - 4}) (\frac{1}{6 - x})

f (x) = x e^{- x}

f (x) = \frac{x - 2}{x}

What is the domain of f(x)=(x^2-3x-4)/(x-4) ?
The domain of f(x)=(x^2-3x-4)/(x-4) is x<4\lor x>4
