Jx, lx + 1, x> 1. 57. Let f(x) = y=x+1 y=f(x) y=x a. Let ɛ = 1/2. Show that no possible 8 > 0 satisfies the fol- lowing condition: 0 < ]x – 1| < 8. |f(x) – 2| < 1/2 whenever That is, for each 8 > 0 show that there is a value of x such that 0 < ]x – 1| < 8 |f(x) – 2| = 1/2. and This will show that lim,1 f(x) # 2. b. Show that lim,1 f(x) # 1. c. Show that lim,1 f(x) # 1.5.
