domain of f(x)=-4/3 x^2+42x

domain

f (x) = - \frac{4}{3} x^{2} + 42 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

x^{3} + 3 x^{2}

y = 7 + ln (x - 9)

f (x) = \frac{1}{x ^{2}}

f (x) = 12 - x^{4}

\frac{x + 3}{2 x - 1}
