1. State the definition of the derivative, and give two interpretations of it.

2. Find the values of x at which the curve y= f(x) has a horizontal tangent.

If you can help me, I would gradually appreciate it (Angel)

1) Google it. Think about the definition.

2) This question makes no sense. You get a horizontal tangent when $\displaystyle \frac{dy}{dx}=0$. To work it out the function $\displaystyle y=f(x)$ has to be known (I think). - Apr 26th 2010, 02:48 PMMscscgrad2011
I did find the first one but I am still lose on the second (Wondering)

There is some information missing.

The curve f(x) has horizontal tangent when its derivative is zero.
