. y = x (x + 2)^2
Find the zeros of each function. State the multiplicity of multiple zeros

Given:

The function is .

To find:

The zeros and their multiplicity.

Solution:

A polynomial is defined as

      ...(i)

where, a is a constant, are zeros with multiplicity respectively.

We have,

It can be written as

         ...(ii)

On comparing (i) and (ii), we get

Therefore, the zeros of the given function are 0 and -2 with multiplicity 1 and 2 respectively.

y=mx+

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
