The axis of symmetry of the graph of y = -(x+4)2 -6 is
1 answer:
Ok so u were close but the answer is actually C and here's why:
The vertex of the parabola is ( -4 , -6 ) And you can tell this since the equation is in vertex form y = a(x - h)^2 + k
Remember axis of symmetry cuts the parabola down the middle meaning it goes through the x axis. x = -4

Answer:
$1080
Step-by-step explanation:
convert % to decimal by multiplying 3.2%x100=0.032
then multiply by initial amount 3000x0.032
then multiply by 2 because it's compounding semiannual
then multiply by 3 because it's over a 3 yr period
do the same for the quarterly compound but multiply by 4 because it's quarterly
over a 3 yr period the quarterly compounded amount will earn:
$504 more than the account compounded semiannual
