Answer:
neither
Explanation:
If f(x) = f(- x) then f(x) is even
If f(- x) = - f(x) then f(x) is odd
Given
f(x) = x - 2x + 5 = - x + 5 , then
f(- x) = - (- x) + 5 = x + 5
Since f(x) ≠ f(- x) then f(x) is not even
- f(x) = - (- x + 5) = x - 5
Since f(- x) ≠ - f(x) then f(x) is not odd
Thus f(x) is neither even nor odd
