domain of f(x)=2x+4

domain

f (x) = 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{6}{x + 6}

f (x) = \frac{1}{x ^{4} - 65 x ^{2} + 64}

f (x) = - x - 14

f (x) = x^{4} - 2 x^{2} + 7

y = 4 x^{2} - 4 x + 1

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