Hey guys

So what I really need help with is not finding the slope it's how do I combine the square root into the F(4+H) part of the derivative formula ?

Let http://webwork.mathstat.concordia.ca...ca33ae5df1.png

The slope of the tangent line to the graph of http://webwork.mathstat.concordia.ca...910e13a9c1.png at the point http://webwork.mathstat.concordia.ca...2e160baab1.png is .

The equation of the tangent line to the graph of http://webwork.mathstat.concordia.ca...910e13a9c1.png at http://webwork.mathstat.concordia.ca...2e160baab1.png is http://webwork.mathstat.concordia.ca...7b883db281.png for

and

Hint: the slope is given by the derivative at http://webwork.mathstat.concordia.ca...a87d2a7e41.png, ie.
