Q. Is the following function even, odd, or neither?f(x)=4−x21Choose 1 answer:(A) Even(B) Odd(C) Neither
Define function and find f(-x): Define the function f(x) and find f(-x).The function given is f(x)=4−x21. To determine if the function is even, odd, or neither, we need to evaluate f(−x) and compare it to f(x).Substitute −x for x in f(x) to get f(−x).f(−x)=4−(−x)21
Simplify f(−x): Simplify f(−x).Simplify the expression inside the parentheses.f(−x)=4−((−x)2)1Since (−x)2=x2, we have:f(−x)=4−x21
Compare f(x) and f(−x): Compare f(x) and f(−x).We have f(x)=4−x21 and f(−x)=4−(−x)21.Since f(−x)=f(x), the function f(x) is an even function.
