multiply both sides by .4 to isolate the x variable.

x = 1.6
Answer:
See below
Step-by-step explanation:
<u>Given function</u>
<u>We can find its factors:</u>
- x³ + 3x² - 7x - 21 =
- x²(x + 3) - 7(x + 3) =
- (x² - 7)(x + 3)
We can conclude that the given polynomial function is fully divisible by (x + 3) and the quotient is (x² - 7)
Also one of zeros of the function is -3
It says decreasing so you have to turn it into a percent (.06%) and then sub tract that from 1. After that you put that into an equation.
