domain of f(x)=(sqrt(4+x))/(3-x)

domain

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

- 4 \leq x < 3 or x > 3

Interval Notation

[- 4, 3) \cup (3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 4

Find undefined (singularity) points:

x = 3

Combine real regions and undefined points for final function domain

- 4 \leq x < 3 or x > 3

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