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

domain

f (x) = lo g_{2} (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

+ \frac{6}{x + 1}

f (x) = lo g_{10} (x - 8)

f (x) = cosh (x^{3} - 8)

3 x + 5

y = \frac{x - 20}{x + 1}

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