domain of f(x)=log_{2}(x^2+64)

domain

f (x) = lo g_{2} (x^{2} + 64)

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find positive values for logs:

- \infty < x < \infty

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

y = \frac{- 3}{5 x + 20} + 7

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

f (x) = \frac{- 1}{x - 1}

f (x) = ln (x) - e^{x} - x

\frac{x + 1}{2 - x}

What is the domain of f(x)=log_{2}(x^2+64) ?
The domain of f(x)=log_{2}(x^2+64) is -infinity <x<infinity
