1. [7 marks] Consider the following graph of f(x): 3 2 -3 -2 3 (a) Use the graph of f(x) to approximate each of the following. Each answer should be a finite number, co, -co, or D.N.E. (does not exist). i) f(-2 ) = ii) lim f(@) = iii) lim f(@) = iv) lim f(x) = _ v) f(2) = vi) lim f(x) = vii) lim f(x) = viii) lim f(a) =_ ix) f(3) = x) lim f(a) = xi) lim f(@) = xii) lim f() = (b) Is f(x) is continuous at r = 3? Explain why or why not
