Using the completing-the-square method, find the vertex of the function f(x) = 5x + 10x + 8 and indicate whether it is a minimum or a maximum and at what point. O Maximum at (1, 8)
O Minimum at (1, 8)
O Maximum at (-1, 3)
O Minimum at (-1, 3)

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.
