d. Repeat steps b and c until either the error for one of the functions is at least a tenth of the original selected function error and you have gone through the process a minimum of three times or you have gone through the process at least five times. [5 marks]3. Using the function selected in Question 2 with the lowest error, do the following:a. Differentiate it using the four step method. [4 marks]b. Integrate the function [3 marks]4. You are required to design a function that will aid in making a twitter post popular.a. What sort of inputs in the function would you need. Give at least five examples.[5 marks]b. What will your output be for the function? [3 marks]c. Describe the process of creating this function with ample examples. [5 marks]

b. For each function that you guess, calculate the error in the function. The error in the function is given by E[f[x} 3(3))2. Where f{x} is the target function that you are trying to discover and 3(1):] is the function you guessed.[5 marks] 33 - 33 33 - 333 3 1 = 2 3(3) =(}2+ 3(3) + 1 3(3) =n+n+1 = 1 3(1) =(1)2+ 3(1) + 1 3(1) = 1+3+1 = 5 3(3) =(3)2+ 3(3) + 1 3(3) =4+3+1 = 11 3(3) =(3f+ 3(3) + 1 - 1'? = - 19 (- 19f = 331 3(3) =9+9+1 = 13 3(4) =31)2 + 3(3) + 1 3(4) = 1s+13+1 = 3(3) =(312 + 3(3) + 3((1) = 3s+15+1 4 + 1 + 64 + 361 + 1156 + RBI]? = 4395 c.
