domain of f(x)=x^4-4x^3-2x^2+12x+9

domain

f (x) = x^{4} - 4 x^{3} - 2 x^{2} + 12 x + 9

- \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, x \geq 0

f (x) = \frac{5}{x ^{2} - 3 x - 10}

f (x) = \frac{2 x}{7 x - 2}

f (y) = - X + 3 + 1

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