Consider the function f(x) =|z-5|+|x+7). (a) Write the function f(I) as a piece-wise defined function, where the pieces are linear functions. (That is, write f(x) using cases, as in Example 4 on page 6, but without using absolute values.) (b) Use part (a) to sketch the graph of the function (by hand)
