Question

Determine whether each of the following functions is even, odd, or neither even or odd. (a) f(x) = x^5 + x (b) g(x) = 1 - x^6 (c) h(x) = 2x - x^4

Answer 1

Answer with Step-by-step explanation:

Even function: If f(x)=f(-x)

Then, the function is an even function.

Odd function: If
`f(x)\\eq f(-x)`

Then, the function is an odd function.

a.
`f(x)=x^5+x`

Replace x by -x

`f(-x)=(-x)^5+(-x)=-x^5-x=-(x^5+x)`

`f(x)\\eq f(-x)`

Hence, the function is an odd function.

b.
`g(x)=1-x^6`

Replace x by -x

`g(-x)=1-(-x)^6=1-x^6`

`g(x)=g(-x)`

Hence, g(x) is an even function.

c.
`h(x)=2x-x^4`

Replace x by -x

`h(-x)=2(-x)-(-x)^4=-2x-x^4`

`h(x)\\eq h(-x)`

Hence, h(x) is an odd function.
