Answer: there was 18 more before the 2:30 stop and after there was 18 less
Step-by-step explanation
We can use the vertex form

to find the equation of the graph. We know that a is the coefficient, and since the graph opens upwards and is slightly stretched vertically, we know that a is 1/3. On the graph, we see that the vertex of the parabola is at (0,-1). Therefore, h is 0 and k is -1.
Our vertex form equation is

Which is D
The answer for the last one at the bottom, 5x + 17 > = 7, the answer is D. x> = -2
For the 1st one up top, the answer is B. 3.
The second one is correct (Radius is the distance from the center to any point on the circle)
