domain of (x-7)(x-9)

domain

(x - 7) (x - 9)

- \infty < x < \infty

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

f (x) = \frac{5 x ^{2}}{5 x - 5}

\frac{19 x}{x - 3}

g (x) = 3 x + 1

f (x) = ln (\frac{1 - x ^{2}}{3 x ^{2} - 5 x + 2})

x^{3} - 6 x^{2} + 11 x - 6
