Question

Use Newton's Method to approximate the zero(s) of the function. Continue the iterations until two successive approximations differ by less than 0.001. Then find the zero(s) using a graphing utility. (Round your answers to four decimal places.)

f(x) = −x³ + 2.7x² + 3.55x − 2.422

Newton's method:	Graphing utility:
x =	x =	(smallest x-value)
x =	x =
x =	x =	(largest x-value)
