domain of (4-x)-(x^2-3x)

domain

(4 - x) - (x^{2} - 3 x)

- \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{1}{x + 19}

\frac{x}{x ^{2} + 3}

(- 4, - 5), (2, 1)

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

f (x) = - x - 1
