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

domain

f (x) = (x - 7) (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{x}{x ^{4} - 1}

f (x) = 2 + x + 1

f (x) = \frac{x ^{4}}{x ^{2} - 11 x + 30}

ln (- x^{2} + 4 x)

y = \frac{x ^{2} - 1}{x ^{2} + 3 x + 1}

What is the domain of f(x)=(x-7)(x-9) ?
The domain of f(x)=(x-7)(x-9) is -infinity <x<infinity
