Q. Determine whether the function f(x)=3x−7x5+2x2 is even, odd or neither.oddneithereven
Write Original Function: To determine if the function is even, odd, or neither, we need to evaluate f(−x) and compare it to f(x).First, let's write down the original function:f(x)=3x−7x5+2x2Now, let's substitute −x for x in the function to find f(−x).f(−x)=3(−x)−7(−x)5+2(−x)2
Substitute −x for x: Next, we simplify the expression for f(−x). f(−x)=−3x−7(−x)5+2x2 Since the exponent 5 is odd, (−x)5=−(x5). The exponent 2 is even, so (−x)2=x2. f(−x)=−3x+7x5+2x2
Simplify f(−x) Expression: Now we compare f(−x) with f(x). f(x)=3x−7x5+2x2 f(−x)=−3x+7x5+2x2 We can see that f(−x) is not equal to f(x) and also not equal to −f(x), because the signs of the terms with x and x5 are different. Therefore, the function is neither even nor odd.
