You would know that

It follows from the sandwich/squeeze theorem: for instance,

The polynomial function with leading coefficient of 3 and root -4, i, and 2 all with multiplicity of 1 is f(x) = 3(x+4)(x-i)(x+2)
<h3>Polynomial function</h3>
The Leading coefficients are the numbers written in front of the variable with the largest exponent.
Roots of a polynomial refer to the values of a variable for which the given polynomial is equal to zero.
The multiplicity is the number of times a given factor appears in the factored form of the equation of a polynomial.
Therefore, the polynomial f(x) = 3(x+4)(x-i)(x+2) has a root -4 , 1 and -2.
The leading coefficient is 3. The multiplicity is all one.

Answer:
Interesting question. I am bad at these questions but I think it is for not standard
Step-by-step explanation:
If im wrong Im sorry
New number - original number
561,000 - 438,000 = 123,000.
Increased number divided by the original number
123,000 ÷ 438,000 = 0.28
Multiply by 100
0.28 x 100 = 28%
The percentage increase would be 28%
