Example 3.5 Use the Newton-Raphson method to estimate the root of f(x) = 0.9x^2 + 1.7x - 5 accurate to ? < 0.001 and given an initial point is x_0 = 1. Use 4 decimal places in all calculations. Example 3.6 Use the Newton-Raphson method to find all numerical solutions of f(x) = e^x - x - 2 in the interval [-2, 2]. All calculation must be in 4 decimal places.

Finding roots with Newton's method For the given function f and initial approximation $x_{0},$ use Newton's method to approximate a root of $f .$ Stop calculating approximations when two successive approximations agree to five digits to the right of the decimal point after rounding. Show your work by making a table similar to that in Example 1. $$f(x)=x^{2}-10 ; x_{0}=3$$
