domain of f(x)=x-4x^2-9g(x)=1x+3

domain

f (x) = x - 4 x^{2} - 9 g (x) = 1 x + 3

- \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{1}{x ^{2} 2 x - 8}

f (x) = \frac{4}{x ^{2} + 100}

f (x) = 7 - x + x^{5}

g (x) = \frac{2}{x - 1}

y = \frac{1}{2} - ln (x^{2} - 4)

What is the domain of f(x)=x-4x^2-9g(x)=1x+3 ?
The domain of f(x)=x-4x^2-9g(x)=1x+3 is -infinity <x<infinity
