can you solve it with matlab program

i want it to be solved from the matlab program as i do not understand good the hand write and is it easy to me if it solved in matlab and there is some explination in the steps thank you

Consider the initial value problem dy dx (a) Without using pre-built commands write an m-file function that uses the second-order Adams-Bashforth method (start the process with a single step using the second-order Runge-Kutta method) to estimate the value of y(1) for a given step size h (b) Use the m-file function built in part (a) to compute an estimate of y(1) using step size 1-0.2 and h 0.1. From these two estimates, approximate the step size needed to estimate y(1) correct to 4 decimal places, explaining your answer. Compute y(1) using the approximate step size and then with half the approximate step size. Comment on your results
