Solution

domain

4 - x

Solution

x \leq 4

+1

Interval Notation

(- \infty, 4]

Solution steps

Find non-negative values for radicals:

x \leq 4

The function domain

x \leq 4

Popular Examples

critical f(x)=4x^{2/3}+x^{5/3}critical points

f (x) = 4 x^{\frac{2}{3}} + x^{\frac{5}{3}}

inverse of f(x)=-1/4 (x+3)^2-5 inverse

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

inflection x^4-6x^3 inflection points

x^{4} - 6 x^{3}

line (0,0),(1/2 ,1)line

(0, 0), (\frac{1}{2}, 1)

domain of f(x)=(x+2)/(x^2-17x+72)domain

f (x) = \frac{x + 2}{x ^{2} - 17 x + 72}
