domain of f(x)=4x^2

domain

f (x) = 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) = 5 x^{3} + 2

f (x) = (x - 1)^{2} (x - 2)^{3}

x^{4} - 12 x^{3} + 48 x^{2} - 64 x

f (x) = \frac{6 x - 1}{2 x + 9}

y - 4 = \frac{4}{5} (x - 5) (- 4 - 2)

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