5. ### Even degree and odd depree polynomial functions?

Hint: show that k(-x) = h(x). Then it follows that k is the reflection of h in the y-axis. If we were looking at odd degree polynomial functions with the same structure, you would find that k(-x) = -h(x), and that k is the reflection of h in the origin (or h...

Since the object is moving at a constant speed of 2m/s, there is zero net external force. Additional 1N is applied. 1 = ma = 2a ==> a=1/2 Vf = Vi +at = 2 + (1/2)*3 = 7/2 m/s
