Help me solve it ASAP

Matlab code pls

Write explicitly any formulas and comments Write a script file for every question. Question 1 (8pts): a) Write a script file to solve equation x2-2x-4 = 0 using solve. Save your results in a paper. Note that the 2 equation to be solved is specified as a string: How to get numerical solutions? b) write a script file to solve equation e-x = sin(x) using fzero, near x-0.5. c) Plot on the same figure the both function y = e-x and y = sin(x) with x = 0-10. Show the solution of question b) on the figure
