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

domain

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

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

\frac{9}{( x + 1 ) ^{2} - 1}

y = \frac{7 x + 3}{x ^{2} + 1}

1 - x
