Answer:
f(-2) = -1
Step-by-step explanation:
f(x) = -x^2 + 3
f(-2) means when x is -2
Shown in the graph below, the point of solution is: (-2,-1), so when x is -2 y is -1
What is all of the rotation rules? (geometry)
1 answer:
Answer:
These are the rules of rotation for geometry.
1) 90° clockwise rotation: (x,y) becomes (y,-x)
2) 90° counterclockwise rotation: (x,y) becomes (-y,x)
3) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
4) 270° clockwise rotation: (x,y) becomes (-y,x)
5) 270° counterclockwise rotation: (x,y) becomes (y,-x)
Step-by-step explanation:
I hope this helps! I also added a picture to make this more clear.
