domain of sqrt(x^2+3)

domain

x^{2} + 3

- \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

12 + 4 y = - 4 x

x^{3} - 9 x^{2} + 15 x + 8

m = - 2, (1, 7)

f (x) = \frac{6}{x ^{2}}

f (x) = 3 sin (\frac{x}{2})
