  1. Check Even Function: To determine if the function f(x)=4x+2f(x) = 4x + 2 is even, odd, or neither, we need to check the symmetry properties of the function. An even function satisfies the condition f(x)=f(x)f(x) = f(-x) for all xx in its domain, while an odd function satisfies the condition f(x)=f(x)f(-x) = -f(x) for all xx in its domain. Let's first check if f(x)f(x) is even.
  2. Calculate f(x)f(-x): We calculate f(x)f(-x) for the given function f(x)=4x+2f(x) = 4x + 2. Substituting x-x into the function, we get f(x)=4(x)+2=4x+2f(-x) = 4(-x) + 2 = -4x + 2.
  3. Compare f(x)f(-x) with f(x)f(x): Now we compare f(x)f(-x) with f(x)f(x). We have f(x)=4x+2f(x) = 4x + 2 and f(x)=4x+2f(-x) = -4x + 2. Since f(x)f(x)f(x) \neq f(-x), the function is not even.
  4. Check Odd Function: Next, we check if f(x)f(x) is odd by verifying if f(x)=f(x)f(-x) = -f(x). We already calculated f(x)=4x+2f(-x) = -4x + 2. Now we need to calculate f(x)-f(x), which is f(x)=(4x+2)=4x2-f(x) = -(4x + 2) = -4x - 2.
  5. Calculate f(x)-f(x): Comparing f(x)f(-x) with f(x)-f(x), we have f(x)=4x+2f(-x) = -4x + 2 and f(x)=4x2-f(x) = -4x - 2. Since f(x)f(-x) does not equal f(x)-f(x), the function is not odd.
  6. Compare f(x)f(-x) with f(x)-f(x): Since the function f(x)=4x+2f(x) = 4x + 2 is neither even nor odd, the correct answer is (C) Neither.
