domain of 3x^3+2

domain

3 x^{3} + 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

y = 5 cos (\frac{1}{4} x)

y = 1.5 ln (x + 5)

2 x - 4 y - 12 = 0

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

f (x) = \frac{1}{x - 4} + \frac{1}{6 - x}
