Question

What is a function that has zeroes at `x=-2` and `x=5`?

Answer 1

`(x+2)(x-5)`

Explanation:

An example is `(x+2)(x-5)` although there are many more I believe.

Since you have 2 zeroes, it means that it cannot be a function of degree `1` or below.

The easiest way to find a function is by applying the rule that `a(x-p)(x-q)=0` where `p` and `q` are the zeroes of the function.

`therefore (x-(-2))(x-(5)`
`=(x+2)(x-5)`
