The first image, because it crosses the origin
Y=-3/5x-6 idk if the picture is going to come up but that’s how i did it
The answer is 22 frames per second, you can find this answer by dividing 110 by 5.
The zeros are at x=8 and x=2. The x-coordinate of the vertex is halfway between, at
x = (8+2)/2 = 5
The y-coordinate of the vertex is f(5) = (5-8)(5-2) = -9
The vertex of f(x) is (5, -9).
