4. Rewrite the following lines of the code to perform the same purpose, but use only one "if" statement. Hint: consider using a logical operator (e.g. AND, OR, NOT). Test your code for the following values: a) x = 2, y = 6, z = 1 b) x = 7, y = 3, z = 10 if x < y if z < 10 end end W = z* (x+y)^2 Upload the .m file for the user defined function on D2L and take screenshots of the above calculations.
