In your lab, a substance's temperature has been observed to follow the function T(X) = (x - 2)3 + 8. The turning point of the graph is where the substance changes from a solid to a liquid. Using complete
sentences in your written answer, explain to your fellow scientists how to find the turning point of this
function. Hint: The turning point of the graph is similar to the vertex of a quadratic function. (10 points)

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Which of the functions graphed below has a removable discontinuity?

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry. how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
