(a) Explain why arcsin x = arctan x 1-x 2 for every x in the interval (-1 , 1). (b) Sketch y = arctan( x-1), clearly indicating all intercepts and asymptotes. 6. Let f ( x ) = 1 + x when x < e x when x (a) Sketch the graph of f and also the graph of its inverse function f-1 oncoordinateaxes (b) Use the graph of the function f-1 that you obtained above to write a formula for f-1 ( x )....
