domain of 4x^2

domain

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^{3} - 2 x + 1

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

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

y = 1 0^{x}

y = \frac{x}{x - 2}
