Answer:
1,000
Step-by-step explanation:
refer to attached.
the number in the thousands place is the number 1.
How we round this number depends on the number immediately to the right of it (i.e the hundreds number)
Case 1: If the number in the hundreds place is less than 5, then we keep the number in the thousands place the same and replace all the digits to the right of the thousands digit by zeros
Case 2: If the number in the hundreds place is 5 or more, then increase the number in the thousands place by 1 and replace all the digits to the right of the thousands digit by zeros
in our case, the hundreds digit is 2, which falls into case 1 above,
hence according to the procedure in case 1 above, we keep number 2 the same and replace everything to the right of 2 with zeros, giving us
1,000

Answer:
option b
1 , 16, 121 , 13456
Step-by-step explanation:
Given in the question a function, f(x) = (x - 5)²
initial value = 4
First iteration
f(x0) = f(4) = (4 - 5)² = (-1)² = 1
x1 = 1
Second iteration
f(x1) = f(1) = (1 - 5)² = (-4)² = 16
x2 = 16
Third iteration
f(x2) = f(16) = ( 16 - 5)² = (11)² = 121
x3 = 121
Fourth iteration
f(x3) = f(121) = (121 - 5)² = (116)² = 13456
x4 = 13456
