Plz solve only (b) within 30-40 mins I'll give you multiple upvote

Extracted text: Testing the concepts of calculus a) Apply 3 steps of the gradient descent algorithm to the following function f(x, y, 2) = a2 - 2y² + 422 keeping (-1 2 0) as the starting point. Show the computation of 7 in each step. b) Draw the graph of f(x) = |2| + |r – 1|+ |r – 2| + |x+3| + - 4 and discuss on the points of continuity and differentiability. c) Find the maximum value(s) of the function f(r, y, z) = x-2y+5z on the units sphere. %3D
