Answer:
Below.
Step-by-step explanation:
0.9 = 90/100 fraction and
= 0.90 as a decimal.
The degree of the polynomial will tell you the max amount of zeros you will have. 11 in this case.
However you can also have 9,7,5,3,1 (keep subtracting by 2)
So the answer is 1.
For 11, the second graph is not a function because the x-values repeat and in a function only the y-values can repeat.
