domain of f(x)=(x-3)(x+5)

domain

f (x) = (x - 3) (x + 5)

- \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

\frac{x + 3}{5 x - 1}

f (x) = 3 - 2 e x - 4

16 - 4 x

f (x) = - 4 x^{2} + 25

f (x) = \frac{1}{- ln ( x ) - \frac{1}{2}}
