How to write a function like it?

1. Create Python functions logistic objective(x,y), dlogistic objective (x,y), d2logisitic.objective(x,y) satisfying the following specifications . All functions expect two arraysumpy arrays x and y where x [1]-xi, ylij-Vi, and {(zi,%))21 C Rx are training data for logistic regression logistic.objective (x, y) returns a function f satisfying the following specifications: f expects a single arrayumpy array b such that b [0] and b [1] = i for some logistic model parameters (A,%) f (b) computes the negative log-likelihood of the parameters (Bo, Bi). That is, i-1 1. Create Python functions logistic objective(x,y), dlogistic objective (x,y), d2logisitic.objective(x,y) satisfying the following specifications .
