Answer 1

Answer:

Answers are below

Step-by-step explanation:

1) Vertex is (1,3). The domain is all real numbers. The range is y ≥ 3. There is a minimum of (1,3). The function decreases when x < 3. The function increases when x > 3. The function is in vertex form.

2) The vertex is (3,2). The domain is all real numbers. The range is y ≤ 2. There is a maximum of (3,2). The function increases when x < 2. The function decreases when x > 2. The function is in quadratic form.

3) Vertex is (0,-3). The domain is all real numbers. The range is y ≥ -3. There is a minimum of (0,-3). The function decreases when x < 0. The function increases when x > 0. The function is is quadratic form.

4) The vertex is (4,1). The domain is all real numbers. The range is y ≤ 1. There is a maximum of (4,1). The function increases when x < 1. The function decreases when x > 1. The function is in vertex form.
