F(x)= -8x²
f(-3)= -8* (-3)²
f(-3)= -8 * 9
f(-3)= -72
So I = Prt
I for interest charge
P for principal ($4,840)
r for rate (6%)
t for time (2 yrs)
So you would then plug the information into the equation.....
I = 4,840*.06*2
I = 580.80
So the answer to your question is $580.80 which is option B
Hope this helps! :)
Use quotient rule to find y"
y" = [-(x-3)-(1-x)]/(x-3)^2 = 2/(x-3)^2
y" = -4/(x-3)^3
-4/(x-3)^3 > 0
(x-3)^3 < 0
x-3 < 0
x< 3
hope this help
