domain of f(x)=2x^2+8x+3

domain

f (x) = 2 x^{2} + 8 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) = x^{4} - 3 x^{3} - x^{2} + 5 x - 1

g (x) = x^{2} - 4

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

f (x) = \frac{x + 1}{x ^{3} - 9 x}

f (x) = \frac{x}{1 - ln ( x - 3 )}

What is the domain of f(x)=2x^2+8x+3 ?
The domain of f(x)=2x^2+8x+3 is -infinity <x<infinity
