So… anyone do the math on that last one? I got $4.55
I got $7.55.
$25
should be $7.00 even unless you’re including taxes
it is $25 actually
$35.00 . . . couldn’t be that cheap
Solving for the derivative I got $25
df(x)/d(x) = 1/5 times 5x^4 – 1/4 times 4x^3 – 2/3 times 3x^2 – 11 times 1. Simplify to df(x)/d(x)= x^4 – x^3 – 2x^2 – 11. Now plugging in the x=3 you get 81 – 27 – 18 – 11=25
Gift Cards normally have a Balance Inquiry number in the back… I’d just call that.
Or stick the equation into something like Google or Wolfram Alpha.
You all need to take some Calculus. He’s asking him to solve for the derivative.
f’(x) = x^4 – x^3 – 2x^2 – 11
f’(3) = 3^4 – 3^3 – 2(3)^3 – 11
= 81 – 27 – 18 – 11
= 25
