domain of f(x)=(sqrt(x+3))/(x-9)

domain

f (x) = \frac{x + 3}{x - 9}

- 3 \leq x < 9 or x > 9

Solution steps

Find non-negative values for radicals:

x \geq - 3

Find undefined (singularity) points:

x = 9

Combine real regions and undefined points for final function domain

- 3 \leq x < 9 or x > 9

y = 4 x - 3

f (x) = 8 + 5 ln (2 x + 3)

f (x) = \frac{5 x - 9}{9 x + 5}

f (x) = - \frac{40 x}{x ^{2} + 25}

f (x) = 2 x^{2} - 12 x + 1

What is the domain of f(x)=(sqrt(x+3))/(x-9) ?
The domain of f(x)=(sqrt(x+3))/(x-9) is -3<= x<9\lor x>9
