Answer:
That's the graph for the function f(x)= -1/2 x^2 + 7
The vertex is f(0) = 7
The equation of the line is y=2/3x + 0
Explanation: The y intercept (where the line crosses the y axis) is 0, and the slope is 2/3 (up two and 3 to the right)
I would go with answer choice C) 200 cause since u said round estimate its actually suppose to be 219 with a remainder of 1 but 200 is the closest to it.
