25. algebraically determine whether the function k(x) = x6 - x2 + 7 is odd, even, or neither. explain your
reasoning

The function is EVEN.

Step-by-step explanation:

For this exercise it is important to remember that:

1. A function f(x) is even if and only if:

for all "x"

2. A function f(x) is odd if and only if:

for all "x"

So knowing that, and given the following function k(x):

You can plug in for "x", order to know if this is even. Then, you get:

Therefore, since:

You can determine that that the given function is Even.

4th option is correct xy=-10
