Q. Determine whether the function f(x)=x6+7x2−1 is even, odd or neither.oddneithereven
Determine Function Type: To determine if the function f(x) is even, odd, or neither, we need to compare f(x) with f(−x). If f(−x)=f(x), then the function is even. If f(−x)=−f(x), then the function is odd. If neither condition is met, the function is neither even nor odd.
Substitute −x in Function: First, let's find f(−x) by substituting −x for x in the function f(x)=x6+7x2−1.f(−x)=(−x)6+7(−x)2−1
Simplify f(−x) Expression: Now, simplify the expression for f(−x). f(−x)=(−x)6+7(−x)2−1 f(−x)=x6+7x2−1
Compare f(x) and f(−x): We have: f(x)=x6+7x2−1f(−x)=x6+7x2−1 Since f(−x)=f(x), the function f(x) is an even function.
