How to make a table of values out of something like y=(X+4)^2-12

[etalns]

Was wondering if anyone could help me out with this and tell me the process of how to make a table of values using this to graph it etc. Would appreciate it a ton, I know how to do it if I have the y-int, and im going from the vertex and attempting to find out what is in the rest of the graph. But not from just using the y = a(X-p)q format.

You want to get a table from a calculator or by hand?

hint: you don't need to make a table of values at all.

if you know how to draw the graph for y=x^2, you should be able to draw y=(X+4)^2-12 easily.

I just pulled that one out of my head, I usually get alot harder ones.

and I need to do it by hand, not permitted to use a calculator for these ones.

Pick a value for one of the variable. Solve it for another variable. List those values in a table. BTW, doesn't matter what values you pick for the first one.

 

[XZeroII]

y=(X+4)^2-12

put 0 in for X and solve. You get Y = 4
put 1 in for X and solve. You get Y = 13
put 2 in for X and solve. You get Y = 24

table would look like

X........Y
---------
0........4
1........13
2........24

easy as that.

what Xzero said.. and then plot those values on a graph paper (if they still sell them....) The more 'dots' you have the better 'picture' you can see.

Depending what you need to do this for, you might have to calculate asymptotes, mins, means, etc.

For the format you gave, it should be a linear relationship, so you just have to solve y for two values of X and draw a line with a strait edge.

curved graphs require more points.
