domain of ln(x^2+3x)

Solution

domain

ln (x^{2} + 3 x)

Solution

x < - 3 or x > 0

+1

Interval Notation

(- \infty, - 3) \cup (0, \infty)

Solution steps

Find positive values for logs:

x < - 3 or x > 0

The function domain

x < - 3 or x > 0

Popular Examples

domain of f(x)=sqrt(7x-x^2)domain

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

domain of f(x)=log_{2}(x(2x-3))domain

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

domain of f(x)=(1955)/(2-|x-1|-|x-3|)domain

f (x) = \frac{1955}{2 - ∣ x - 1 ∣ - ∣ x - 3 ∣}

domain of sqrt(5+4x-x^2)domain

5 + 4 x - x^{2}

domain of f(x)=sqrt((x^2+2)/(x^2-2))domain

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