Answer:
I imagine you aren't using calculus, so:
A: the leading term is 
, so it opens upwards.
B. First coordinate of the vertex is 
, the second coordinate we'll find by replacing the value: 
C. Quadratic formula or if you stare at the equation long enough you can rewrite the equation as 
. At this point the x intercepts are the zeroes of the function, or -6 and 2.
D. The y-intercept is the value of the function at 0, or the constant term: -12
E. The graph has a minimum since the curve opens upwards.
With the 15% coupon, you will get $1,875. (Because 15% of the bond's price $12,500 is $1,875.) Solution: 0.15 x 12500 = 1875
So $1,875 is to be divided by the actual price of the bond which is $10,750. (1, 875 ÷<span> 10,750 = 0.1744 convert this to percent to get the rate of return)
0.1744 = 17.44 %
The rate of return is 17.44%.</span>
