Long answer:
The domain is all real numbers except -6 and 0. Hence, domain D: x ≠ –6, 0
Hence the range is all real numbers except -3 and 3. Hence, range R: (–∞, –3) ∪ (3, ∞)
Given the following functions:
First we need to get the composite function f(g(x))
Get the domain
The domain the values of x for which the function exists. The function cannot exists at when x = -6 and x = 0
Hence the domain is all real numbers except -6 and 0. Hence, domain D: x ≠ –6, 0
The range is the value of y for which the function exists. The function cannot exists at when x = -6 and x = 0
Hence the range is all real numbers except -3 and 3. Hence, range R: (–∞, –3) ∪ (3, ∞)
