Ineed for an algebra ii exam i have tomorrow.
1. what is the relationship between the domain and range when f(x)=sqrt. x-h +k?
2. discriminant and solutions of 20x^2+40x+10=0?
3. possible zeros using zeros theorem for f(x)=x^3+7x-9?
4. domain/function of 4x/3x^2-3x-6?
5. what does b effect in f(x)=ab^x+c?
6. if k is the constant in k^2x^3-6kx+9, is it divisible by x-1?
7. what's the extraneous solution of sqrt. x+3=2x by x^2?
8. describe imaginary units and graphing functions?
9. if (x^2+2xy+y^2)(x+y)= 64 what is (x+y)?
any is appreciated so much.

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.
