domain of 2x^2+x-8

domain

2 x^{2} + x - 8

- \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) = \frac{6}{x}

(0, - 2), (- 5, 3)

\frac{x ^{2} + 5}{x ^{2} - 2 x - 15}

f (x) = ln (x) + ln (9 - x)

- 2 x^{2} + 6000 x
