everthing in matlab! thank you !

2. Develop a fully commented bisection function. Within your function, ensure that you are passing in an anonymous function. 3. Solve the roots problems to find all the roots between -1 and 3 for the following equation: f= sin(x')+x2-2x-009 4. Engineers use thermodynamics in their work. The following equation relates the zero- pressure specific heat of dry air Cp [kJ/(kg K)1 to temperature [K: Cp =0.99403+1.67 1x10-4T +9.721 5x10-8T2-95838x 10-1 1T3 +19320x10-14T4 Make a plot of Cp versus temperature from T = 0 to 1300K. Then, find the temperature that corresponds to a cp of 1.1 kJ/(kg K)
