In this we know all three zeros and one point from which the graph pass.
So we will let specific cubic polynomial function of the form

As we know zeros are that point where we will get value of function equal to zero. So it is basically in form

SO in given question zeros are (2 , 0) , (3, 0) and (5,0)
So we can say

So required equation is

Now we have one point (0 , -5) from which graph passes.
So we say at x = 0 , f(x) = -5



So required equation of cubic polynomial is

For finding y - intercept we simply plugin x = 0 in given equation.
As we know at x = 0 , value of function is -5.
So y - intercept is -5.
The first step to determine the percentage of increase is to
compute for the difference of consumer price index in value.
231.11 (consumer price index for 2012) – 211.4 (consumer
price index for 2007) = 19.71 (increase)
To compute for the percentage of increase, you need to
compare the increase to the consumer price index for 2007.
19.71/211.4 = 9.3% increase
The constant would be 35 because a variable added onto it would make it a
Answer:
4.6 or if you rounded it would be 5
