For A do I put 4 or put 4^2 (16)?

  a = -4,  b = 8,  c = 3

This is because the general template is ax^2+bx+c

Matching up the terms gets us what is shown in bold. The x's are not involved as part of a,b,c. We just focus on the numbers in front.

The graph is shown below. I used GeoGebra to make the graph.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
