Begin by fully investigating x = y²and x² + y² = 25
as follows.
1. Without using Desmos, make a table and a graph
for each above equation.
2. Marabel and Lissa are working on this problem.
Marabel is making a table forx = y². For an x-value
of 4, she finds a y-value of 2. Lissa is watching and
says, "Wait! When x is 4, there is also another possible
value for y." What does Lissa mean? Look back at
your tables and decide if there are more points you
could add.
3. Fully describe the graphs of x = y² and
x² + y² = 25.
