domain of f(x)=sqrt(x^2)-4+sqrt(9-3x)

domain

f (x) = x^{2} - 4 + 9 - 3 x

x \leq 3

Interval Notation

(- \infty, 3]

Solution steps

Find non-negative values for radicals:

x \leq 3

The function domain

x \leq 3

\frac{1}{2 + e ^{4 x}}

(sin (x))^{\frac{1}{3}}

x^{2} - 9 x + 14

\frac{5}{4 x ^{\frac{1}{6}}}

f (x) = - 5 - x
