Find a 90 degree counterclockwise rotation?
follow this formula (x,y)->(-y,x)
Does a transformation ever change the shape of a figure?
Yes. The transformation from y = f(x) to y=f(2x) will compress the shape along the x-axis by a factor of 2.
What kind of transformation would add 4 to the x-values of every point in a shape and subtract 2 from the y values of every point in a shape?
The transformation from y = f(x) to y = f(x - 4) - 2
What happens to the x- coordinate during a 180 degree rotation?
depends on the centre of rotation if it's about the origin the x coord is multiplied by -1
Which rule describes a transformation across the x axis?
You have to add on the number that you want to transform the graph by. For example to move the graph 2 units along the x-axis the transformation would be f(x+2).
The transformation f x y y x is what degree rotation?
90 degree anticlockwise.
Find a 90 degree counterclockwise rotation?
follow this formula (x,y)->(-y,x)
What transformation is represented by the rule (x y) (y -x)?
It is an anticlockwise rotation through 90 degrees.
Does a transformation ever change the shape of a figure?
Yes. The transformation from y = f(x) to y=f(2x) will compress the shape along the x-axis by a factor of 2.
The equation of rotation geometric transformation?
In two dimensions, the equations of rotation about the origin are: x' = x cos t - y sin t y' = x sin t + y cos t. where t is the angle of rotation, counterclockwise.
What is the formula of 180 degree counterclockwise rotation?
Oh, dude, it's like you just take the original coordinates and swap them around while changing the sign of one of them. So, for a 180-degree counterclockwise rotation, you just flip the signs of both x and y. Easy peasy lemon squeezy!
What degree clockwise rotation goes from xy to -xy?
180 degrees in the plane perpendicular to the xy plane. In general, no rotation in the (x, y) plane will take it to (-x, y) unless x = y (or -y) and, in that case it is a 270 degree clockwise rotation.
What kind of transformation would add 4 to the x-values of every point in a shape and subtract 2 from the y values of every point in a shape?
The transformation from y = f(x) to y = f(x - 4) - 2
What happens to the x- coordinate during a 180 degree rotation?
depends on the centre of rotation if it's about the origin the x coord is multiplied by -1
What are geometric transformation?
shown on graphs . 3 types : translation , rotaation , reflection x , y - -x ,y = reflection over y axis x,y- y,-x = reflection over x- axis translation= x,y - x+ or - horizontal change , y+ or - vertical change Perfect reflection= x,y - y,-x 180 degree rotation = x,y - -x , -y 90 degree clockwise rotation=x,y - y , -x 90 degree counter clockwise rotation = x,y - -y,x when graphing transformations , label the new image points as primes . When theres more then one prime , up the amount. Ex: A(1,0) becomes A'(A prime) (-1,0) hope this helps!
How do you find 270 degree clockwise rotation?
(x,y) to (x,-y). You would keep the x the same, but turn the y negative. This is actually the rule for a 90 degree counterclockwise rotation, but they're the same thing, they would go to the same coordinates.
