domain of y=log_{3}(x^2-9)

domain

y = lo g_{3} (x^{2} - 9)

x < - 3 or x > 3

Interval Notation

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

Solution steps

Find positive values for logs:

x < - 3 or x > 3

The function domain

x < - 3 or x > 3

y = x^{2} + 8 x + 15

y = lo g_{3} (x^{2} - 1)

- 3 x + 9

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

f (x) = \frac{x ^{2} - 4}{x ^{2} + 6}

What is the domain of y=log_{3}(x^2-9) ?
The domain of y=log_{3}(x^2-9) is x<-3\lor x>3
