A group of students is arranging squares into layers to create a project. The first layer has 5 squares. The second layer has 10
squares. Which formula represents an arithmetic explicit formula to determine the number of squares in each layer ?

Start from the parent function
In the first case, you are computing
In the second case, you are computing
, you translate the function horizontally,
units left if
and
units right if
.
On the other hand, when you transform , you translate the function vertically,
units up if
and
units down if
.
So, the first function is the "original" parabola , translated
units right and
units up. Likewise, the second function is the "original" parabola
, translated
units left and
units down.
So, the transformation from to
is: go
units to the left and
units down
20... 5÷ 1/4
