Question

for ech parabola A. identify the vertex B. give the minimum or maximum value of the function C. find the domain and range.

Answer 1

A. From the picture, the vertex is at (-2, 6)

B. From the picture, the vertex is a maximum. The maximum is 6

C. The domain is the set of all possible values of the x-variable. For any parabola, the domain is (-∞, ∞)

The range is the set of all possible values of the y-variable. From its maximum, the range of the parabola is (-∞, 6]
