domain of f(x)=cot(pi/3+2x)

domain

f (x) = cot (\frac{π}{3} + 2 x)

\frac{π}{2} n \leq x < \frac{π}{3} + \frac{π}{2} n or \frac{π}{3} + \frac{π}{2} n < x < \frac{π}{2} + \frac{π}{2} n

Interval Notation

Solution steps

Take the denominator(s) of

cot (\frac{π}{3} + 2 x)

and compare to zero:

x = \frac{π}{3} + \frac{π}{2} n

Periodicity of

cot (\frac{π}{3} + 2 x) : \frac{π}{2}

Combine period:

\frac{π}{2} n \leq x < \frac{π}{2} + \frac{π}{2} n

and undefined points.

The domain is

\frac{π}{2} n \leq x < \frac{π}{3} + \frac{π}{2} n or \frac{π}{3} + \frac{π}{2} n < x < \frac{π}{2} + \frac{π}{2} n

3 x + 12

3 x + 10

f (x) = \frac{3 x + 5}{x ^{2} + 3 x - 28}

f (x) = x^{2} + 7

\frac{x + 2}{5}
