Dy/dx=2x+2
So velocity will be zero when 2x+2=0, x=-1
Since d2y/dx2=2, it has a constant positive acceleration of 2, so that when dy/dx=0 it is at an absolute minimum value for f(x), which is also the vertex.
y(-1)=1-2+3=2
So the vertex is at (-1,2), which is an absolute minimum so the parabola opens upwards.
And by symmetry we can say that f(0)=f(-2)=3 so you have another two points that you can see (-2,3) and (0,3)
But how many laps did she walk
This sequence is doubling the sequence and adding half. When n is your number, you could find the next number in your sequence by plugging in the number:
2n+0.5n
To find the 4th term, we need to plug in 50.
2*50+0.5*50=125
Now, we need to find the 5th term, so we plug in 125.
2*125+0..5*125=312.5
To find the 6th term, we plug in 312.5.
2*312.5+0.5*312.5=781.25
So, the next 3 terms are 125, 312.5, and 781.25
