domain of f(x)=log_{10}(x^2-4)

domain

f (x) = lo g_{10} (x^{2} - 4)

x < - 2 or x > 2

Interval Notation

(- \infty, - 2) \cup (2, \infty)

Solution steps

Find positive values for logs:

x < - 2 or x > 2

The function domain

x < - 2 or x > 2

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

5 x - 3

f (x) = lo g_{10} (2 x + 1)

\frac{6 - x}{x + 9}

f (x) = 3 x - x^{3}

What is the domain of f(x)=log_{10}(x^2-4) ?
The domain of f(x)=log_{10}(x^2-4) is x<-2\lor x>2
