Evaluate the expression when x = 2, y = -3, and z = -1.
Find the values of the expression for x = -2, -1, 0, 1, 2
This question is asking us to evaluate the expression for five different values. It may be easiest to do this in chart form.
Which of these values (-2, -1, 0, 1, 2) makes this equation true?
Just like the previous problem, it is probably useful to make a chart.
