What this does is reapplies the formula

Unformatted text preview: x sub n - f(x sub n-1)/ f'(x sub n-1) in order to get a good approximation of a y value given an x value that is surmised based on looking at the function and in this case given that our y value equals 2.5 million, drawing a line from that point to the first point at the function and drawing another point directly down. The x value that is assumed is now plugged in to the formula and recalculated until an insignificant decimal repeats itself. x sub n being the assumed x value the neumerator being the function or the curve that we used to get the approximate x value at 2.5 million the denominator being the derivative of the function or the slope of the tangent line of the function F(37.5) Tangent line- Is a line that passes through a single point in the same direction as that point in the line....
