Question

(a) degree 4, 3 zeros, 3 turning points, and negative leading coefficient

Answer 1

Step-by-step explanation:

Use this polynomial.

$- x {}^{4} +9x {}^{3 } + 13 {x}^{2} - 45x - 50$

A degree 4 means our leading coefficient looks like.

${x}^{4}$

Since our degree is 4, our turning points would be 3.

Since we have three roots, we need two single roots and a double root.

A negative leading coefficient would have a negative sign in front of it.
