1. The problem statement, all variables and given/known data

Need help with all of question 8 , any help would be appreciated thanks :D




2. Relevant equations



3. The attempt at a solution

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.

You DO know that the slope of the tangent line equals the derivative, don't you? Well, in 8(i) you have y = (3x^2 - x - 3)^3. What is preventing you from taking the derivative?

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.

Find the derivative (which is the slope), then use point slope form:
y-y1=m(x-x1)
