Solved 1 Assume That F X X 3 X 3 For Each Real Number X Chegg Com Answer (1 of 4) f(x)=\sqrt{9x^2} 9x^2\ge 0 x^2–9\le 0 (x3)(x3)\le 0 \text{So domain}\, 3,3 For range replace f(x) by y, f(x) always be positve number y^2=9x^2 x^2=9y^2 x=\sqrt{9y^2}The "" means "such that," the symbol ∈ means "element of," and "ℝ" means "all real numbers" Putting it all together, this statement can be read as "the domain is the set of all x such that x is F(x)=3x-1 domain and range
