We are given with the equation <span>f(x) = ax3 + bx2 + cx + d
Substituting, (3,11)
</span><span>11= 27a + 9b + 3c + d
</span><span>@(5, 9)
</span><span>9 = 125 a + 25 b + 5c + d
@</span><span>(4, 10)
</span><span>10 = 64 a + 16 b + 4c + d
@inflection point, second derivative is equal to zero
</span><span>f'(x) = 3ax2 + 2bx + c
</span>f''(x) = 6ax + 2b = 0
when x is 4, 24 a + 2b = 0 or 12a + b = 0.
There are 4 equations, 4 unknowns: answer is
<span>0.5 x^3 - 6x^2 + 22.5 - 24 = 0</span>
You multiply all of them together and then dived by 100 and that's your answer

Answer:
They Would be if they Have a pattern from left to right such as +2 or -5.
Step-by-step explanation:
If an example is counting up from 15 to 31 and 0 to 8 the pattern is Adding Two. So if the numbers decrease or increase in a certain way, then you can find out what it is and thn bam, your answer to the question.
Change in y over change in x
