i need help with all the questions please

Write a script which does all of the following in order: 1. Assign the function f(x) = x In (2x) + sin(5x) - cos(x) to f(x). Make sure you declare x as symbolic first. 2. Find the derivative of xf (4- x)2 and assign the result to the new function g(x). 3. Calculate 8(-2) and assign the result to the variable a1. 4. Find the second derivative of sin(2x + 2) and assign the result to the new function j(x). cos (1-x) x2 5. Assign the function h(x) = log10 (2-x) + x + 5 6. Calculate h" (3) and assign the result to the variable a2. 7. Find the second derivative of e2x5x - 1) at x=-2 and assign the result to the variable a3 8. Assign k(x) = 2x3 + 2x2 - x + 7 and find all critical values (x-values where the slope is zero) for k(x). Assign the result to the variable a4 9. Assign m(x) = sin x- cos x and find all x-values where the second derivative is zero. Assign the result to the variable a5. 10. Use solve and diff to find the two x-values where the slopes of the graphs of y = x2 + 3x + 1 and y=x? - 2x + x + 3 are the same. Assign the result to the variable a6
