\f(1 point) Use Newton's method to find the second and third approximation of a root of +at3=0 starting with $1 = -1 as the initial approximation. The second approximation is *2= The third approximation is *g=\f(1 point) Use 5 iterations of Newton's Method with the given initial approximation to approximate the root of the functionAll answers should be given to 5 decimal digits of accuracy. f()=25, xg=2.9 (1 point) Use Newton's method to approximate the value of as follows: Let 1 = 3 be the initial approximation. The second approximation *2 is and the third approximation *3 is
