Question

Find the first three iterates of f(x)=-3x - 7 if x0 = -8.?
A. x1 = 17, x2 = -58, x3 = 167
B. x1 = 21, x2 = -61, x3 = 170
C. x1 = -17, x2 = 58, x3 = -167
D. x1 = -21, x2 = 61, x2 = -170

Answer 1

so if x_0 =-8, what is the eq for x_1?

Answer 2

i really don't know.

Answer 3

uhm ok, well if I rewrite it as this, any ideas \[x_n=-3x_{n-1}-7\]
any ideas?

Answer 4

hint, let n=1 to start
