1 The graphs of y=（3/2)^x - 1 and y=x intersect at points Q(0,0) and A.
a. Sketch these graphs on the same diagram.
b. Using logarithms, find a suitable iterative formula that can be used to find the coordinates of the point A.
c Calculate the length of the line OA, giving your answer correct to 2 significant figures. Give the value of any iterations you calculate to a suitable number of significant figures.
