Hello, Blueazulim06!
Topsquark gave you the best advice.
Let me try to make it clearer . . .
I have this graph of a function, but not the equation for the function.
The question wants me to graph the derivative.
Suppose your graph looks like this: Code:
*
* *
* *
* * *
* *
* *
*
Estimate the slope at a number of points. Code:
m=0
m=1 * m=1
* *
/ \
m=2 * * m=2
/ \
* * *
* * m=2
\ /
m=1 * * m=1
\ * /
m=0
Those are the values we plot on the "derivative graph". Code:

2+ * *


1+ * *


 +     *      *  


1 * *


2+ *

Hope this helps . . .
