domain of 3x^2+x+5

domain

3 x^{2} + x + 5

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

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

- \infty < x < \infty

f (x) = ln (x - 1)

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

f (x) = \frac{( 4 x - 1 )}{2 x + 9}

f (x) = \frac{x ^{2} + 3 x - 28}{x ^{2} - 16}

5 x^{3} - 1
