domain of f(x)=sqrt(2+|x|)

domain

f (x) = 2 + ∣ x ∣

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find non-negative values for radicals:

- \infty < x < \infty

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

- \infty < x < \infty

4 x^{3} + 7 x^{2} - 10 x - 8

y = 0.5 (x^{2} - 10 x - 5)

\frac{x ^{2} - 13 x + 36}{x ^{2} + 25}

f (x) = \frac{x ^{2} - 36}{x ^{2} - 25}

\frac{( 6 + x ) ( 3 + x )}{- 3 - 4 x}

What is the domain of f(x)=sqrt(2+|x|) ?
