domain of-sqrt(x^2+4)

domain

- x^{2} + 4

- \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

y = 3 x + 3

f (x) = x^{4} + 8

sin (2 x)

2 x (x - 1)

f (x) = - 16 t^{2} + 64 t + 720
