domain of f(x)=3x^4-2x^2+5

domain

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

- \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

\frac{1}{5 x - 20}

f (x) = ln (2 x) - 3

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

f (x) = - \frac{8 x}{x ^{2} - 4}

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