Answer:
option d
13 , 173 , 29933
Step-by-step 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
