Given that the domain of F (x) is [- 3,5], what is the domain of K (x) = f (- x) + F (2x + 5)?

Given that the domain of F (x) is [- 3,5], what is the domain of K (x) = f (- x) + F (2x + 5)?

In order to understand this problem, we must first make clear the following problems: 1, the function f (x) and f (- x), f (2x + 5) are not the same function; 2. The function f (x) and f (T), f (U) are the same function; 3, the domain of definition always points to the independent variable x; 4, f (- x); f (2x + 5) is the composite function of F, also known as the second generation F, let t = - XF (- x) = f (T)
