Which of the following graphs is a polynomial function with x-intercepts of (-3,0)(-1,0), and (2,0)?
2 answers:
The intercepts of the third degree polynomial corresponds to the zeros of the equation
y = d*(x-a)*(x-b)(x-c)
Where a, b and c are the roots of the polynomial and d an adjustment coefficient.
y = d*(x+2)*(x)*(x-3)
Lets assume d = 1, and we get
y = (x+2)*(x)*(x-3) = x^3 - x^2 - 6x
We graph the equation in the attached file.

The simple interest on the principal amount of $725 at a rate of 3.25% for 6 months is $736.78
<h3>What is simple interest? </h3>Simple interest is calculated on the loan principal amount or the initial deposit into a savings account. It can be determined by using the formula:
where:
- P = principal = $725
- R = rate = 3.25%
- T = time = 6 months = 0.5 years
S.I = $736.78
