The answer is A because zeros of polynomial functions are found by setting each factor equal to zero and solving for x. The zeros of a function will be the opposite sign of the numbers inside each factor.
Answer:
3.553774
Step-by-step explanation:

h
works out to 3.553774
<u> Answer I got for this was 16.
Subtract the 1/4 from the 3/4 and get 2/4, simplified: 1/2
You should have 1/2 h -9 = -1 by now,
Then add nine to the other side, getting 8.
You should have 1/2 h = 8.
Then divide 1/2 by 8.
8/1÷1/2 ---> 8/1 × 2/1 (you flip the fraction when you divide)
So your answer is 16!
Hopefully that helped!</u>
