Use Newton's Method to approximate the x-value of the point of intersection of the two graphs of f(x) = 3x + 1 and g(x) = Vx+5 to 5 decimal places. Use your calculator to find the x-value of the intersection to 5 decimal places and calculate your error until your approximation matching the calculator's.
