domain of f(x)=3x^2+2x+1

domain

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

- \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) = 3^{x - 2}

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

f (x) = lo g_{3} (2 x - 3)

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

f (x) = \frac{2 x}{x - 4}

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