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

domain

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

- \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 (\frac{1 - x}{1 + x})

\frac{7 x}{x - 2}

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

\frac{x}{x + 14}

f (x) = \frac{( x + 2 )}{x ^{2} - 121}
