domain of f(x)=sqrt(5x^2+3)

domain

f (x) = 5 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

f (x) = ln (x) - 4

y = \frac{5 x}{x ^{2} + 2}

f (x) = \frac{2 x + 6}{- 3 x + 3}

f (x) = \frac{3}{2} x^{2} - 3 x - 1

\frac{18 x}{x - 9}
