The red line is 180 degrees. So the arcs on top of the circle all equal up to 180 degrees. the number 72 doesn't really matter cause you're trying to find out the angle of DCE which is on the other side of the circle. So you gotta find the arc length of DE which is 68 because 180-112=68. So to find the angle, you have to divide the opposite arc length by two, which is 34.

The parent function for quadratic equations is as followed:
where a for vertical stretches, b is for horizontal stretches, h is the x value of the vertex, and k is the y value of the vertex.
The vertex of the is (-3, -2), so we can write the first part of the equation:
To determine if the graph has any stretches, we can check how changes to the x coordinate affect the y value. If there are no stretches, as the x coordinate moves away from the vertex, the y coordinate should be x^2 from the vertex. If we test with a couple points on the graph, wee see that this is true, so there are no stretches. The answer is:
