The functionf(x)=x3 – 6x2+9x+15f(x)=x^3\ –\ 6x^2+9x+15f(x)=x3 – 6x2+9x+15is local maxima at
x = 1
x = 3
no point of maxima and minima

For times t > 0, a particle moves on the x axis with its acceleration defined by a(t) = 6t – 2. If the velocity of the particle is -7 at t = 1, then at what time is the particle at rest?
t = 4
t = 1
t = 2
t = 4/3
How is our confidence level from 1-5?
1 = "Oh god help me that was complete nonsense and makes no sense"
2 = "some of that seemed familiar but I don't think I could do it"
3 = "i know this stuff but could do with some practice"
4 = "i can do this... I'm pretty sure at least"
5 = "step aside Mr. Tim! there's a new calculus expert in town"
