Q. Determine whether the function f(x)=−7x4−6x2+2x6 is even, odd or neither.evenoddneither
Check Even Symmetry: To determine if the function is even, odd, or neither, we need to check the symmetry properties of the function. A function f(x) is even if f(−x)=f(x) for all x in the domain of f. A function f(x) is odd if f(−x)=−f(x) for all x in the domain of f. If neither condition is met, the function is neither even nor odd.
Replace x with −x: First, we will check if the function is even. We do this by replacing x with −x in the function and simplifying.f(−x)=−7(−x)4−6(−x)2+2(−x)6
Simplify Expression: Now we simplify the expression by calculating the powers of −x. f(−x)=−7((−x)4)−6((−x)2)+2((−x)6) Since the powers are all even, the negative signs will be canceled out. f(−x)=−7(x4)−6(x2)+2(x6)
Compare to Original Function: We compare this expression to the original function f(x).f(−x)=−7(x4)−6(x2)+2(x6) is the same as f(x)=−7x4−6x2+2x6.Since f(−x)=f(x), the function is even.
