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

domain

f (x) = 9 x - 7 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) = 3 sin (\frac{6 x}{7} + 2 π)

\frac{x + 6}{x - 5}

x + 1

f (x) = 3 x^{2} - 8

f (x) = \frac{3 x + 4}{- 5 x - 7}
