Question 207120: Could someone help me with these;
1) Could someone show me how to graph x^2/16-y^2/25=1
2) I also dont know how to graph the ellipse x^2+4y^2=64
3) Graph y=3^x
Could someone show me how to graph all three (I am a total loser when it comes to graphing -_- )

For 1 and 2, use Function, Insert Relation
-------------
To do them manually, as you'd have to do on a test:
Solve for y
x^2/16-y^2/25=1
y+=+5%2A%28sqrt%28%28x%5E2-16%29%2F16%29%29
Pick values for x and solve for y. Remember + and minus values, too.
eg
x y
4 0
-4 0
5 15/4
-5 15/4 etc.
--------------
Plot the points (4,0), (-4,0), 5,15/4) etc
