Which option below correctly describes the domain of b(x) = 81- x and explains why the range of bis not all real The domain is a real numbers greater than or equal to 81 The range is not all real numbers because the square root of a negative number is not a real number The domain is a real numbers greater than or equal to 81 The range is not all real numbers because the square root symbol applied to a non-negative number is non-negative. The domain is all real numbers less than or equal to 81 The range is not all real numbers because the square root symbol applied to a non-negative number is non-negative The domain is all real numbers less than or equal to 81 The range is not all real numbers because the square root of a negative number is not a real number

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
