Answer:
Applied the definition and the limit.
They had the same result, so the function is continuous.
Step-by-step explanation:
At function f(x) is continuous at x = a if:
In this question:
At x = 3.
Since 
, f(x) is continuous at x = 3.
A=pir^2
c=2pir
a=pir^2=16
pir^2=16
divide both sides by pi or about 3.141592
r^2=5.0929581789406507446042804279205
sqrt both sides
r=2.2567583341910251477923178062431
circumference=2pir
circumference=2pi(2.2567583341910251477923178062431)
c=4.5135166683820502955846356124862pi
about 4.5pi square cm
answer:
(-2,7) is reflected to (-2,-7)
(3,9) is reflected to(-3,9)
(7,2) is reflected to(7,-2)
(-3,-9)is reflected to (-3,9)
-3^4 (Three to the Fourth power)
