x \geq - 3

The function domain

x \geq - 3

Popular Examples

domain of f(x)=3sqrt(x-2)domain

f (x) = 3 x - 2

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

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

critical f(x)=(x+1)(x-4)^2 critical points

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

m

inverse of f(x)=log_{b}(x)inverse

f (x) = lo g_{b} (x)
