Answer: Determine whether (–x)3 + 5(–x) + 1 is equivalent to x3 + 5x + 1.
To determine if a function is even, we need to check if f(-x)=f(x).
Solution: Alyssa is incorrect.
In fact
.
If we cross-multiply the above equation, we have:


Therefore, they are equal.
Also, if we reduce the given fractions, we have:

And

Since both the fractions reduced to
, therefore fractions are equivalent.
