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

domain

f (x) = 9 - 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

d o main f (x) = \frac{( 2 - x )}{x + 3}

p er i o d i c i t y 3 + t^{5} + sin (π t)

r an g e \frac{1}{4} x^{3} - 6

d o main f (x) = \frac{10 x ^{2}}{x ^{4} + 25}

r an g e f (x) = \frac{4}{x ^{2} - 25}

What is the domain of f(x)=9-4x^2 ?
The domain of f(x)=9-4x^2 is -infinity <x<infinity
