Rod, how can I check the answers to the piecewise function is correct. Thanks mate, I appreciate your help.

Question

How would you check the answer is right?

Answer 1

You can draw the function and check the continuity that way. You should get a continuous line/curve. You can plug in the border values, where the pieces join, to make sure that the values at the end points of the segments are the same for adjacent segments. There should be no holes or jumps as you go from one segment to the next.
