it is \[f (x)=x ^{2}\times(x-2)^{3}\] ???

derive the function and evaluate in 1 and you'll have the pendient, replace 1 in the first function and you have the point, so you have the pendient and one point, you can get the equation (y-a)=m(x-b), sorry for my english I speak spanish XD

How do I start to evaluate the function?

  • anonymous
I mean, derive*

step by step ...first: replace 1 in the function, what is the result?
anonymous
  • anonymous
-1

ok you have the point (1, -1) , remember the equation of a rect you need a point and the pendient, you have a point, now you need the pendient in x=1, the pendient in x=1 is the derivate of the function evaluate in 1, .. can you derive the function?

I don't know past here...

ok the derivate of the function is : \[2x(x-3)^{3} + x ^{2}(3(x-2)^{2})\] if you evaluate in 1 the result is -13, I think, so you have the pendient m= -13 and the point (a,b)= (1, -1) .. the rect is (y-a)=m(x-b) and replace the values

sorry i have a mistake is 2x(x-2)^3 but is the same idea
