How fast is the y coordinate changing/ Project Management
1. A point is moving on the graph of y=ex+x+x in such a way that its x coordinate is always increasing at a rate of 3 units per second. How fast is the y coordinate changing when the point crosses the x axis?
2. A point is moving on the graph of x3+y2=1 in such a way that its y coordinate is always increasing at a rate of 2 units per second. At which point(s) is the x coordinate increasing at a rate of 1 unit per second?
