domain of f(x)=log_{3}(x-9)

domain

f (x) = lo g_{3} (x - 9)

x > 9

Interval Notation

(9, \infty)

Solution steps

Find positive values for logs:

x > 9

The function domain

x > 9

f (x) = \frac{x ^{3} - 9 x}{x + 2}

f (x) = \frac{π}{2} + sin (x)

f (x) = \frac{7}{x + 2}

(1, 11), (13, - 5)

f (x) = \frac{5 x + 25}{2 x + 7}

What is the domain of f(x)=log_{3}(x-9) ?
The domain of f(x)=log_{3}(x-9) is x>9
