Below, I added what the graph of (x^2)-2 looks like...
The answer is A. (0, -2); Minimum
The answer is 1/2lbs, here's how.
3/4x2/3=6/12 reduced to 1/2lbs.
$1100 x 1.021^7 = $1272 (whole number.)
the $1100 is the original amount of money put in the bank with the 1.021 being the interest rate. this was put to the power of 7 to represent the years the money will be in the account.
