domain of f(x)=12-x-9/x ,x>0

domain

f (x) = 12 - x - \frac{9}{x}, x > 0

x > 0

Interval Notation

(0, \infty)

Solution steps

Set the domain to the given interval

x > 0

Find undefined (singularity) points:

No real undefined points

Join undefined points with the domain:

(x < 0 or x > 0) and x > 0

x > 0

(x - 1)^{2} + 5

(x - 1)^{2} + 3

f (x) = lo g_{3} (8 - 2 x) + 1

(\frac{1}{2})^{x - 2} - 2

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