Convergence-Bisection

Question 1
The convergence of the bisection method is
A
Cubic
B
Quadratic
C
Linear
D
none
Question 1 Explanation: 
The convergence of the bisection method is very slow. Although the error, in general, does not decrease monotonically, the average rate of convergence is 1/2 and so, slightly changing the definition of order of convergence, it is possible to say that the method converges linearly with rate 1/2.
Note:For the bisection you simply have that ε​ i+1​ /ε​ i​ =1/2, so, by definition the order of convergence
is 1 (linearly).
