Which rules could describe the rotation? Select two options. R0, 90° R0, 180° R0, 270° (x, y) → (–y, x) (x, y) → (–x, –y)

1. R0, 90° (counterclockwise) R0, 270° (clockwise)

2. R0, 180° (clockwise and counterclockwise) rotation

Step-by-step explanation:

Here, we want to state the type of rotation in the activity

1. (x,y) turning to (-y,x)

This rotation is ;

90 degrees counter-clockwise

and;

270 degrees clockwise

2. (x,y) to (-x,-y)

we have this as;

180 degrees clockwise rotation and 180 degrees counter-clockwise rotation

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
