Anthony has a square-shaped, wooden board. To build a door, he uses the board and cuts 3 feet off of its width. The new area of the wooden board is given by the expression below, where x represents the length in feet.
x(x-3)
Which statement best describes the term (x - 3)?
Answer:
D = {x|x∈R|x≥-4}
R = {y|y∈R|y≥-2}
Use the vertex to determine the domain and range.
The outside of the root is positive so it continues upward. [y = -√x the graph goes down from vertex.]
The inside of the root is positive so it continues rightward, [y=√-x the graph goes left from vertex.]
In the equation y = √(x + 4) – 2, the vertex is (-4, -2). The x-coordinate of the vertex is negative the value in the root.
Answer:
11
Step-by-step explanation:
X = -2....this is a vertical line where x will always be -2 no matter what y is.
So any points that have a -2 as the x value, no matter what the y value is, will be a correct answer.
