domain of f(x)=x^3+5x^2-1

domain

f (x) = x^{3} + 5 x^{2} - 1

- \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) = x 2 x + 1

f (x) = - x^{4} - 5 x^{3} + 6 x - 2

f (x) = 6 x^{2}

f (x) = ln (5 x + 2)

f (x) = 289
