domain of f(x)=log_{10}(-x-20)

domain

f (x) = lo g_{10} (- x - 20)

x < - 20

Interval Notation

(- \infty, - 20)

Solution steps

Find positive values for logs:

x < - 20

The function domain

x < - 20

f (x) = \frac{1}{1 - ∣ 2 x ∣}

\frac{2 x + 5}{x - 1}

f (x) = \frac{x ^{2} + 1}{x ^{2} - 16}

\frac{2}{t + 4}

g (x) = 3 x - 1
