Homework Statement
Given the equation y= f(x) , at a certain point the slope of the curve is 1/2 and the x-coordinate decreases at 3 units/s. At that point, how fast is the y-coordinate of the object changing?
The Attempt at a Solution
Dy/dx = f ' (x) dx/dt
Would that be the correct way to begin this problem? Then plug in 3 for dx/dt and 1/2 for f'(x)?
Thanks
