domain of-(x+1)(x-2)

domain

- (x + 1) (x - 2)

- \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{\frac{1}{x}}{1 + \frac{1}{x}}

f (x) = \frac{x - 10}{x ^{2} - 16}

8 x - 1704

- 5.5

f (x) = 7 x^{2} + 8 x - 15
