Write f(x) in a non-factored way from polynomial equation f(x)=(x+2)(-x+3)(x-2)?
Lelu [443]

Answer:

f(x) = -x³ + 3x² + 4x - 12

Step-by-step explanation:

f(x)=(x+2)(-x+3)(x-2)

Step 1. Use the difference of two squares

(x + 2)(x - 2) = x² - 4

f(x) = (-x + 3)(x² - 4)

Step 2. Long multiplication

x² - 4

<u>-x  + 3               </u>

-x³           + 4x

<u>      + 3x²         - 12</u>

-x³ + 3x² + 4x - 12

f(x) = -x³ + 3x² + 4x - 12

Belinda wants to invest in an option that would help to increase your investment value by the greatest amount in 20 years. Will
Molodets [167]

Step-by-step explanation:

Part A, Option 1 is a exponential function while option is a linear equation.

Part B, Let y=b*a^(x) be the function for option 1. At x=1, y=1100 and at x=2, y=1210. 1100=b*a and 1210=b*a^2. Dividing them both we get, b=1.1 and a=1000. y=1000*(1.1)^(x). For option 2, it's a linear equation with a function y(x)=1000+100x.

The 20 year difference would be immense. With option 1, Belinda will get $6727.5 whereas with option 2, they will end up with $3000
