domain of f(x)=-x^2+2x-19

domain

f (x) = - x^{2} + 2 x - 19

- \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

- 3 cos (x)

+ 5 - \frac{2}{x}

2 x^{2} - 2

\frac{4}{( \frac{1}{x} ) - 3}

f (x) = 3^{- x} - 5
