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

domain

f (x) = f (x) = x - 2 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

y = sec (\frac{1}{2} x)

e^{- l n (x)}

20 - x

y + x = - 4 x + (x - 2)^{2}

f (x) = x^{4} + \frac{4}{3 x ^{3}}
