Suppose we have a training set with m=3 examples,plotted below.Our hypothes is representation is hθ(x)=θ1xh_{\theta}(x) = \theta_1x, with parameter θ1\theta_1. The cost function J(θ1)J(\theta_1) is J(θ1)J(\theta_1)=12mi=1m(hθ(xi)yi)2{1\over2m}\sum\nolimits_{i=1}^m(h_\theta(x^i) - y^i)^2. What is J(0)J(0)?<image 1>



(A) 0


(B) 1/6


(C) 1


(D) 14/6


Answer with the option's letter from the given choices directly. No punctuation.
