Answer:
The first three iterations are 1.67, 1.56 and 1.52
Step-by-step explanation:
Given the function g(x)=1/3x+1
To get the first threw iteration with initial value of x = 2
First iteration at x= 2:
g(2) = 2/3+1
g(2) = (2+3)/3
g(2) = 5/3 = 1.67
Second iteration will be when x = g(2) = 5/3
g²(2) = g(5/3) = 1/3(5/3) + 1
g²(2) = g(5/3) = 5/9 + 1
g²(2) = g(5/3) = 14/9 = 1.56
Third iteration will be at when
x = g²(2) = 14/9
g³(2) = g(14/9) = 1/3(14/9) + 1
g³(2) = g(14/9) = 14/27 + 1
g³(2) = g(14/9) = 41/27 = 1.52
The first three iterations are 1.67, 1.56 and 1.52
