Make a table for the rule y =
that includes x‑values from −1 to 10. What happened?
Graph the rule on graph paper.
What kind of growth does the rule show? How do you know?
Is this relationship a function? How do you know?
What happens when you substitute a negative answer for x?
Does this make sense?
The graph has no value for x < 0.
Do the y-values increase by a constant amount?
Is there one output for every input?
