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

domain

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

f (x) = \frac{x}{5 x + 16}

f (x) = \frac{1}{9.3 x - 1.4 x ^{2}}

5 - 4 x

f (x) = \frac{2 x ^{2} + 1}{3 x - 5}

f (x) = \frac{x ^{2} + 2 x - 3}{( x - 1 ) ( x ^{2} - 4 )}

What is the domain of f(x)=x^3+2x-4 ?
The domain of f(x)=x^3+2x-4 is -infinity <x<infinity
