domain

3 x + 9

Solution

x \geq - 3

+1

Interval Notation

[- 3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 3

The function domain

x \geq - 3

Popular Examples

domain of f(x)=(sqrt(t-5))/(3t-18)domain

f (x) = \frac{t - 5}{3 t - 18}

domain of f(x)=sqrt(x+3)-1/x domain

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

extreme f(x)=4x^3-x^4 extreme points

f (x) = 4 x^{3} - x^{4}

domain of sqrt((x^2)/(x^2-1))domain

\frac{x ^{2}}{x ^{2} - 1}

inverse of f(x)=(2x^2-7x+2)/(x-4)inverse

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