domain of x^2-8x-9

domain

x^{2} - 8 x - 9

- \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}{3} - 2 x

f (x) = - 2 x (x - 2) (x - 6)

f (x) = \frac{- 10}{5 + x}

2 π

f (x) = 0.5 \cdot (- 3.75) - \frac{2}{8}
