Hi i would like your help solving this, if you could do it on paper it would be easier to read and understand for me, thank you.

1. a) What conditions must be met in order for lim f(x) to exist? [1] x->a b) Given f(x) = vx-8 , does lim f(x) exist? Using your answer to a), justify your response. [2] 2. Use the definition of continuity to answer the following question: Is the function f(x) = vx-8 continuous at x =8? Explain. [2] 3. Sketch the piecewise function to the right. x if x 0
