domain of f(x)=(7x)/(x-8)

domain

f (x) = \frac{7 x}{x - 8}

x < 8 or x > 8

Solution steps

Find undefined (singularity) points:

x = 8

The function domain

x < 8 or x > 8

f (x) = x^{2} ∣ x ∣ + 9

f (x) = \frac{x ^{2} - x - 20}{x - 2}

\frac{x - 1}{2 x ^{2} - 15 x + 25}

f (x) = \frac{1}{x ^{2} + 5 x - 14}

f (x) = 7 + (10 + x)^{\frac{1}{2}}

What is the domain of f(x)=(7x)/(x-8) ?
The domain of f(x)=(7x)/(x-8) is x<8\lor x>8
