Is there a function somewhere Bus? :)

tkhunny · Answer

Is there a function or are we just pulling things out of the air?

amtran_bus · Answer

How in the world!

amtran_bus · Answer

Oh sorry. x^3.

tkhunny · Answer

Some reason why we are NOT to calculate the EXACT derivative?

BTW - Please show you work.  You have not yet done that.

amtran_bus · Answer

Well, here is the problem. It wants me to estimate with a calc, but I don't know how. So I rather do it the regular way. Your gonna have to help me to even start.

zepdrix · Answer

What does that mean estimate with a calculator?
Using the graph of the function or some other approximation technique? :o

amtran_bus · Answer

Estimate the values of 
f '(0), f '1
f '(2), f '(3), and f '(4)
 by using a graphing device to zoom in on the graph of f. (Round your answers to one decimal place.)

tkhunny · Answer

You calculator will display the tangent to a point on the curve that it draws.  Perhaps you can estimate the slope of that line.  It's a purely visual thing.

Make sure your x- and y-scales are the same.  You WILL be confused, otherwise.
