domain of f(x)=-(4x^2)/3+55x

domain

f (x) = - \frac{4 x ^{2}}{3} + 55 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

9 - x^{3}

(9 - x^{2}) (x + 1)

f (x) = \frac{x ^{2} - 1}{x + 1} - x^{3} - x

\frac{x - 7}{x + 2}

y = 1 - ∣ x ∣
