Answer 2

@amorfide a.Write functions for the following transformations using function notation. Choose a different letter to represent each function. For example, you can use R to represent rotations. Assume that a positive rotation occurs in the counterclockwise direction.
• translation of a units to the right and b units up
• reflection across the y-axis
• reflection across the x-axis
• rotation of 90 degrees counterclockwise about the origin, point O
• rotation of 180 degrees counterclockwise about the origin, point O
• rotation of 270 degrees counterclockwise about the origin, point O

Answer 3

• translation of a units to the right and b units up
this means you are going A in the positive x direction
so if I had f(x)=x
translating a in the positive X direction means I get F(x+a)= (x-a)
translating b units up means you are going b in the positive Y direction
so if I had
f(x)=x
f(x)+b = x+b

so to get translation a in positive x and b in positive y I get
f(x)=x
f(x+a)+b=(x-a)+b
• reflection across the y-axis

to reflect a function across the y axis
f(x)=x
f(-x)=(-x)
• reflection across the x-axis

reflection across x axis
f(x)=x
-f(x)= -(x)

Answer 4

I don't know how to describe rotations
