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.

Please help I found this one a bit confusing

Brums [2.3K]

Answer:

7.2

Step-by-step explanation:

To reach point D from point C, you need to add 4 to the x-value of point C and take away 6 from the y-value. These numbers are the sides of the hypothetical triangle.

The Pythagorean Theorem states that $a^2+b^2=c^2$ . If we plug the side lengths in for a and b, we get $4^2 + 6^2 = c^2$ . This can be simplified to $16+36=c^2$ , or $52 = c^2$ . If we root both sides, we find that c is equal to $\sqrt{52}$ , which is slightly more than 7, at around 7.2.
