Determine the root of f(x)= x - 2e^(-x) by:

Using the bisection method. Start with a= 0 and b= 1, and carry out the first three iterations.

Using the secant method. Start with the two points, x_1 = 0 x_2 = 1 and carry out the first three iterations

Using Newton's method. Start at = 1, and carry out the first three iterations
