Answer:
Increased by a factor of 4
Step-by-step explanation:
The original circumference is:
C1 = 2 * pi * r1
The new circumference is:
C2 = (2 * pi * r2)
"circumference that is 4 times larger than the original"
(2 * pi * r2) = 4 (2 * pi * r1)
Rewriting:
r2 = 4r1
Answer:
The radius of the original circle is:
increased by a factor of 4

f(3) = 1.9
Solution:
Given function:

To find f(3):
Substitute x = 3 in the given function.


Let us first simplify
.
Apply exponent rule: 

The value of
. (using calculator)


Substitute this value in f(3).


f(3) = 1.9
Hence the value of f(3) is 1.9.
