Heres a math thingy because im slow and dk how to do it :) Draw a line between each description and the transformation it describes.
1. Shift up, down, right and/or left (Rotation)
2. A flip over line (Reflection)
3. A turn about a point (Dilation)
4. A change in size (Translation)

Actually Welcome to the concept of Types of shifting.

1.) Shift up, down, right and/or left - Translation

2.) A flip over line - Reflection

3.) A turn over a point - Rotation.

4.) A change in size - Dilation

is only a line? i think so

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
