Write a polynomial function in standard form with zeros at −3, −1, and 1.

f(x) = (x + 3)(x + 1)(x − 1)

f(x) = x^3 + 3x^2 − x − 3

f(x) = x^3 − 3x^2 − x + 3

f(x) = (x − 3)(x − 1)(x + 1)

Step-by-step explanation:

The given polynomial has zeros at:

x=−3, x=−1, and x=1.

This means that:

x+3, x+1, and x-1 are all factors of this polynomial.

The factored form of this polynomial is :

We expand the last two factors using difference of two squares.

This is the standard form because it is now in decreasing powers of x.

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)
