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

domain

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

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find positive values for logs:

- \infty < x < \infty

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

y = sin (2 x)

f (x) = 5 (\frac{1}{2})^{x} - 8

arcsin (lo g_{\frac{1}{2}} (ln (x)))

lo g_{2} (x - 1) + 3

y = 15 - 3 x

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