Question

Iterations question one, thanks for the help :)

Answer 1

option d

13 , 173 , 29933

Explanation:

Given in the question a function, f(x) = x² + 4

initial value x0 = -3

4 times iteration means f(f(f(x)))

First iteration

f(x0) = f(-3) = (-3)² + 4 = 13

x1 = 13

Second iteration

f(x1) = f(13) = (13)² + 4 = 173

x2 = 173

Third iteration

f(x2) = f(173) = (173)² + 4 = 29933

x3 = 29933
