Reflections are a type of transformation that move an entire curve such that its mirror image lies on the other side of the x or y axis.
A vertical reflection is given by the equation y=−f(x) and results in the curve being "reflected" across the x-axis. A horizontal reflection is given by the equation y=f(−x) and results in the curve being "reflected" across the y-axis.
Reflection is one of the four basic rigid motions.
Four basic rigid motions:
1.Reflection
2.Glide Reflection
3.Rotation
4.Translation
Answer: The correct expression is (A) 6b.
Step-by-step explanation: Given that Serena is writing an expression that is equivalent to (12ab - 6b), but she has not completed it.
The incomplete expression is ?(2a - 1).
We are to find the missing term from the above incomplete expression.
We have
Thus, the complete expression is 6b(2a - 1).
Option (A) is correct.
So if f(-3), then x = -3.
Substitute.
y = -(-3)^2 + 6
= -(9) + 6
= -3
