Question

Determine the first five iterates of the function \(f(x) = 2x + 10\) if the initial value is -12.

Answer 1

ok real question is this
does it start at \(-12\) or does it start at \(-14\) ??

Answer 2

I think it starts at -12 since it says "the initial value is -12. "

Answer 3

thanks @satellite73 for posting..

Answer 4

ok
i thought \(-14\) but i would not bet more than $3 on it

Answer 5

@Zarkon what do you think?

Answer 6

@AravindG any opinion?

Answer 7

I guess this says otherwise, hmm

Answer 8

I'm looking at pg 263

Answer 9

In regard to this question, is the given initial value the initial value of X?

Answer 10

yeah i would say \(x_0=-12\) so first is \(x_1=-14\) but that is just a guess really

Answer 11

let's assume that the initial value of X = -12.
It's not completely clear about this point, but we'll make this assumption.

Answer 12

good assumption, statellite

Answer 13

Even I believe they are asking for the function values. The assumption is right it seems.

Answer 14

i think @jim_thompson5910 has it at \(-14\) from the book
thanks

Answer 15

yeah that book says -14 is the first iterate
