SUMMARY

The discussion focuses on the relationship between the graphs of a function y, its first derivative y', and its second derivative y''. Specifically, for the function y = x^3, the first derivative is y' = 3x^2 and the second derivative is y'' = 6x. Key insights include that the graph of y' indicates critical points where y' = 0, and the sign of y' reveals whether the graph of y is increasing or decreasing. This analysis is foundational in curve sketching techniques.

Homework Statement



Say y = x^3

Then: y' = 3x^2
y'' = 6x


My question is... Let's say I graphed y y' and y''. Do these graphs give us any info about the anti derived graph?

For instance just by looking at the y' graph can I gather up any info for y graph?

Yep. Where y' is 0, the slope is zero and the graph has a critical point. Where y'>0, you know the graph is going up. Where y'<0, you know the graph is going down.

This is all covered in curve sketching.
