A point P ( x , y ) moves along the graph of the equation y = x 3 + x 2 + 2. The x -values are changing at the rate of 2 units per second.
A point
P(x, y)
moves along the graph of the equation
y = x3 + x2 + 2.
The x-values are changing at the rate of 2 units per second. How fast are the y-values changing (in units per second) at the point
