Which equation graphs as the parabola? A)

ƒ(x) = x2 –8x – 9

B)

ƒ(x) = x2 – 9

C)

ƒ(x) = x2 + 8x + 9

D)

ƒ(x) = –x2 + 9

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
