Consider the function:
f(x) = 7 - 28x + 42x2 - 28x3 + 7x4:
Write a script findPolyRoot.m to nd, as accurately as you can, the root of f(x) near x = 2. Your script must store the root of the function in the variable root. You may use any of the other functions you have written for this lab, but you are not allowed to use any of Matlab'sbuiltin root nding functions.
