Reflection across the x-axis:

y = − f ( x ) y = -f(x) y=−f(x) The concept behind the reflections about the x-axis is basically the same as the reflections about the y-axis.
Answer:
If
is the transformed function, then the parent function
has been shifted up vertically by 4 units and horizontally right by 2 units
Step-by-step explanation:
Assume the function is
is the parent function.
A vertical shift,b units up will transform the function to
.
A horizontal shift
units.

For instance, if
, b=4, and a=2 units.
Then the transformed function becomes:

C= πr²
C= 3.14×8²
C=3.14×64
C=200.96
Answer:
P = 100
Area = 625
Step-by-step explanation:
Area = s^2
sqrt(area) = sqrt(s^2)
area = 25*25
sqrt(25*25) = sqrt(s^2)
s = 25
P = 4*s
P = 4 * 25
P = 100
Area = s^2
s = 25
Area = 25^2
Area = 625
