domain of f(x)=(9-2x)(7-2x)x

domain

f (x) = (9 - 2 x) (7 - 2 x) x

- \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

1 - \frac{9}{x ^{2}}

4 x - 28

f (x) = 2 x^{2} + 5 x - 12

f (x) = x^{2} - 4 + 9 - 3 x

\frac{1}{2 + e ^{4 x}}
