The limit of a function gives the value of the function as it gets infinitely closer to an x value. If the function approaches 4 from the left side of, say, x=-1, and 9 from the right side, the function doesn't approach any one number. The limit from the left and right exist, but the limit of a function can't be 2 y values.

The absolute value is a special case of parentheses. We do the work inside the parentheses 1st. The absolute value gets applied to the result, not the parts. Consider this numeric example: |3 (5)-9|. 1) Using PEMDAS: Mulitply, substract, then do absolute value once there is one number. |3 (5)-9| = |15 -9| = |6| = 6. AboutTranscript. The graph of y=k|x| is the graph of y=|x| scaled by a factor of |k|. If k<0, it's also reflected (or "flipped") across the x-axis.
