Explanation:
Given function is
.
Now we need to rewrite that equation in standard form.
Given equation is a polynomial function. So to write that in standard form, we need to rearrange terms in descending order of exponents of the variable (x).
We see that exponents of variable x are 2, 1 and 0.
Terms are already written in descending order of exponents.
Hence final answer is given function itself.
