Answer:
1) 2) x=2, multiplicity 1 x=-7, multiplicity is 3.
Step-by-step explanation:
1) The zeros of this function are the roots of it. Which number added to -2 will return 0 for the first factor (x-2)? Similarly, which one added to -7 for the second factor (x+7)³ will return 0?
2) The multiplicity of a function is the number of repeated times, a factor of a polynomial function appears in its factored form. So,
The factor is (x+7) whose multiplicity is 3, then x=-7, multiplicity=3
The factor (x-2), then x=2, multiplicity =1
