domain of f(x)=(x^2)/(x-9)

domain

f (x) = \frac{x ^{2}}{x - 9}

x < 9 or x > 9

Interval Notation

(- \infty, 9) \cup (9, \infty)

Solution steps

Find undefined (singularity) points:

x = 9

The function domain

x < 9 or x > 9

f (x) = \frac{8 x - 8}{x + 2}

f (x) = \frac{x}{( x ^{2} - 16 )}

f (x) = 0.6 x + 6.5

\frac{x - 5}{3}

y = \frac{x ^{2} + 2 x - 8}{x - 1}

What is the domain of f(x)=(x^2)/(x-9) ?
The domain of f(x)=(x^2)/(x-9) is x<9\lor x>9
