You wish to write a script that will analyze the following function: f(x)=(x^(2)cos(3x+1))/(xlog_(10)3x) Write the m-file required to define this as a Matlab function. Call the function 'fun_call' and pass the function x and return the value y. The input x may be a scalar variable or a vector. Write the Matlab command(s) to find a zero of fun_call near x=2.5, and assign the solution to the variable xzero
