domain of f(x)=28x^3

domain

f (x) = 28 x^{3}

- \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) = \frac{5 x + 25}{x}

3 x + 9

f (x) = x^{4}

y = 4 x - 3

\frac{( - 3 - 3 )}{( 5 - 2 )}
