domain of f(x)=ln(x^2-2|x|+2)

domain

f (x) = ln (x^{2} - 2 ∣ x ∣ + 2)

- \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

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

y = 0.15 (x - 8230) + 823

x^{2} (x + 6) (x + 2)^{3} (x - 4)^{3}

6 x^{2} - 24 x - 30

\frac{2 x ^{2}}{3 x ^{2} + 1}
