Final answer:
To write the polynomial y²+3y⁴−7y+2y³−4 in standard form, we rearrange the terms in order of decreasing powers of y.
Step-by-step explanation:
The polynomial y²+3y⁴−7y+2y³−4 can be rearranged in standard form by arranging the terms in order of decreasing powers of y. This means writing the term with the highest power of y first, followed by the term with the next highest power, and so on.
So, rearranging the terms of the given polynomial in standard form, we get:
3y⁴+2y³+y²-7y-4
