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

domain

f (x) = lo g_{2} (x^{2})

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find positive values for logs:

x < 0 or x > 0

The function domain

x < 0 or x > 0

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

\frac{x ^{2}}{x + 3}

f (x) = x^{2} + x + 1

g (x) = \frac{x}{9 x ^{2} + 8 x - 1}

5 x + y = 4

What is the domain of f(x)=log_{2}(x^2) ?
The domain of f(x)=log_{2}(x^2) is x<0\lor x>0
