Q. Is the following function even, odd, or neither?f(x)=3x−xChoose 1 answer:(A) Even(B) Odd(C) Neither
Determining Function Symmetry: To determine if the function f(x)=3x−x is even, odd, or neither, we need to check the symmetry properties of the function. A function is even if f(−x)=f(x) for all x in the domain, and it is odd if f(−x)=−f(x) for all x in the domain.
Checking for Even Symmetry: First, let's check if the function is even. We calculate f(−x) and see if it is equal to f(x).f(−x)=3−x−(−x)=−3x+xNow we compare this to f(x):f(x)=3x−xClearly, f(−x) is not equal to f(x), so the function is not even.
Checking for Odd Symmetry: Next, let's check if the function is odd. We calculate f(−x) and see if it is equal to −f(x).We already have f(−x) from the previous step:f(−x)=−3x+xNow we calculate −f(x):−f(x)=−1×(3x−x)=−3x+xWe see that f(−x) is equal to −f(x), so the function is odd.
