domain of f(x)=x^2-4x-1

domain

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

4 x^{2} - 36

y = x^{2} - 5 x + 6

\frac{x ^{4} - 3 x ^{3} + 4}{3 x ^{2} - 7 x - 20}

f (x, y) = 2 - y^{2}

f (x) = \frac{x}{1 - ln ( x - 5 )}
