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
Misha would combine 3x-2x and-8-7
F(x) = 20000 (1-0.15) power x
So
f(x) = 20000 (0.85) power x

selected=8
=8-5=3
=75/100×3
=3/4×3
=9/4
=2 1/4
