so find the derivative of those functions, and plug in x= whatever point they asked about. that's the slope at that point. so for the first one, find f'(x), and then plug in 1.

The other are all similar: either use derivative formulas you have covered in class, or look in the book for related material that you may not have covered explicitly, or else consult tables of derivatives, etc. Basically, you just need to start. RGV

Do you know how to chain rule?

Find the derivative (which is the slope), then use point slope form:
yy1=m(xx1)
