Let f RR be defined by f(x)=x+√√1-x. Use the definition of limit to prove that lim f(x) = 1. x→1- Let f be a function with domain R, let L be a real number, and let c be a positive real number. Prove that if lim f(x) = L, then lim 7f (cx² x) = 7L. You may not use any limit laws in x→0 x→0 this problem. Work directly from the definitions of these limits only.
