domain of-x-3

domain

- x - 3

- \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

t - 2

- 2 x - 1

f (x) = \frac{x}{x ^{2} - 3 x - 18}

(1 + \frac{100}{0.5})^{2 x}

f (x) = \frac{x - 9}{x ^{2} + 64}
