f(x)=2x^3-3x^2+1
i graphed the function and the derivative.

a)use the graph to determine the exact point(s) where f has a horizontal tangent line.
b)give the values of f'(x) at each of the points found in part a

Question

f(x)=2x^3-3x^2+1 
i graphed the function and the derivative.

a)use the graph to determine the exact point(s) where f has a horizontal tangent line.
b)give the values of f'(x) at each of the points found in part a

anonymous · Answer

they would be zero

anonymous · Answer

what about part b

anonymous · Answer

that is part b
the tangent lines are horizontal where the derivative is zero

anonymous · Answer

what about a) i got that the points were (0,1) and (1,0).. is that right?

anonymous · Answer

i don't know but it is easier to do the second part first
find the zeros of the derivative (easy as it is a quadratic)and that will tell you the x values of the horizontal tangents
