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

domain

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

- \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}{x + 3 - 3}

x^{2} + 8 x

f (x) = \frac{3}{cos ( x ) - 1} + 10

f (x) = \frac{1}{4 - t ^{2}}

f (x) = ln (2 - x) + 1
