Can anyone solve this ???? ~_~


when x = 0 the answer is 4
x= 1 is 5
x=2 is 9
x=3 is 18
x=4 is 34
x=5 is 59
x=6 is 95

its the previous answer + x*x

Impractical Math is by far my weakest subject.

I will never, ever, use analytical geometry in my life. So sorry bud, can't help you here.

f(x) = 4 IFF x = 0
f(x) = f(x-1) + x^2 IFF x > 0

amirite?

but if x= 1 then

f(x)= (1-1) +1^2 and that doesn't =5 .....right :?

also are you allowed to some up with 2 solutions in these problems :?


Kitt mad me sad today :(

No. It's recursive.

if x = 1, then
f(x) = f(1-1)+ 1^2
f(x) = f(0) + 1
f(x) = 4 +1
f(x) = 5

since f(x) = 4 when x = 0

Well, since i assumed it was recursive, I needed a base case. Since you never mentioned negative numbers and i'm too lazy to do the work, I just stopped at f(0) = 4 and didn't worry about negative numbers.

So, the base case is f(0) = 4 and all you have to say is that this function only works for real, positive integers.

But I have no idea what the question to the problem is, so this is all assumption that it solves your problem.

No. It's recursive.

f(x) = f(1-1)+ 1^2
f(x) = f(0) + 1
f(x) = 4 +1
f(x) = 5

since f(x) = 4 when x = 0




AHHHHHHH your smart! :D

i get what you are saying now im assuming it works for the other numbahs

now that thats out of the way i can enjoy my life again... :D
