Unformatted text preview: Project 6 MAC 2311 1. Examine the piecewise-defined function below, and sketch the graph carefully on the axes: g ( x ) = e- x x < x = 0 2- 1 x < x < 1 1 x > 1 Evaluate the following limits: lim x →- g ( x ) = lim x → + g ( x ) =-∞ lim x → g ( x ) = lim x → 1- g ( x ) = 1 lim x → 1 + g ( x ) = lim x → 1 g ( x ) = 1 Although we have not discussed this yet, test your intuition and understanding of limits and limit notation by guessing the value of the following limits: lim x →∞ g ( x ) = 1 lim x →-∞ g ( x ) = ∞ 2. Sketch the function h ( x ) = x 2- 6 x + 5 x- 5 . (Consider simplifying first.) x- 1 , x 6 = 5 What continuous function is identical to h ( x ) for all x except x = 5 ? Evaluate the limit: lim x → 5 h ( x ) . What type of discontinuity does this function have? hole at ( 5 , 4 ) 3.
