The answer would be 3 and 4 over 5
1. "the graph has the same zeros" : so let a be the "triple" root of the cubic polynomial function.
2. So f(x)=

3. Don't forget that the expression might have a coefficient b as well, and still maintain the conditions:

4. Now, f(0)=-5 so




5. the function is

where a can be any real number except 0
I am currently doing this right now, make them equal each other, then follow what i do:
Answer:
Length of crab in x years = x + 2
Step-by-step explanation:
Since the crab grows 1 inch per year, and it would grow:
1 inch in the 1st year
2 inches in the 2nd year
3 inches in the 3rd year
4 inches in the 4th year
.
.
.
And so on.
However, in order to find the total length, you need to remember that the crab is originally 2-inches long. So the total length after x years would be the number of inches it grew over the years (x) + the length before the growth (2).
Thus, Length of crab in x years = x + 2
