The problem
The Diagram shows the graph of y=x^3-12x+17
A is the maximum point on the curve
C is the minimum point on the curve
The curve crosses the y-axis at B
For the equation find dy/dx, y=x^3-12x+17 (DONE)
Heres the problem
find the gradient of the curve at B
now what am I supposed to do here?
this is what i tried but I am not sure if its right
3x^2-12=17
make x the subject therefore giving
x=[tex]\sqrt{}29/3[/tex]
so is that right or..?
