2. Reformulate the equation e' = 4.r3 - 2x + 4 so that it has the canonical form of a root finding problem 3. As a first step towards finding the roots of a function, you can plot the function. Where do you find the approximate positions of the roots in such a plot? 2. Reformulate the equation e' = 4.r3 - 2x + 4 so that it has the canonical form of a root finding problem 3.
