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

domain

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

y = sin (2 x ln (x)) (sin^{2} (2 x))

(1, 1), (8, - \frac{3}{4})

f (x) = sin (x)

\frac{e ^{x}}{x ^{2}}
