domain of f(x)=(2x^2-x-1)/(x^2+4)

domain

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

- \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{4 x + 4}{3 x + 11}

7 x - 3 y = - 3

ln (5 x)

x^{2} - \frac{1}{x}

2 x + 1
