|2x–1|-|2x+1| f (x) : (a) Find the domain and the range of f. (b) Does the limit lim -0 f (x) exist.? If the limit exists, find its value. If not, show how the limit fails to exist. (c) Do the limits lim, x→∞ f (x) and lim f (x) exist? x→-∞ (d) Find the values of x (within the domain of this function) at which f' (x) is undefined. Show how the derivative fails to exist at these values of x. Use the limit definition.
