domain of f(x)=(sqrt(x+1))/(x^2-16)

domain

f (x) = \frac{x + 1}{x ^{2} - 16}

- 1 \leq x < 4 or x > 4

Interval Notation

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

Solution steps

Find non-negative values for radicals:

x \geq - 1

Find undefined (singularity) points:

x = 4, x = - 4

Combine real regions and undefined points for final function domain

- 1 \leq x < 4 or x > 4

f (x) = lo g_{6} (2 x - 4)

f (x) = 9 sin (x - 5) + 8

\frac{x ^{2} - 4}{x ^{2} - 1}

- 2 x + 1

What is the domain of f(x)=(sqrt(x+1))/(x^2-16) ?
The domain of f(x)=(sqrt(x+1))/(x^2-16) is -1<= x<4\lor x>4
