Answer:
y = 4(x - 1)²(x + 4)³
Step-by-step explanation:
There are two different types of zeros: 1 and -4. Since we know 1 is a zero of multiplicity 2, and the function is a 5th degree polynomial, -4 is of multiplicity 3. Leading coefficient is 4, so now we can construct.
y = 4(x - 1)²(x + 4)³
Hope this helps!
