how to find deriv of graph

[spare dirge]

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

...what's the derivative?

As in, what is a derivative?

[south knoll]

A derivative is described as either the rate of change of a function, or the slope of the tangent line at a particular point on a function

there's your answer then, that's how you find it w/ a graph

Ok deriv of 4 is 1/2 and slope of 1 is undefine

?

[pine wave]

clearly slope at 1 is 0

it's a horizontal line at 1

and yes, it's a line of slope 1/2 at 4
