Answer:
domain is (-∞,∞)
(-∞,0) U(0,∞)
Step-by-step explanation:

The domain is the set of x values for which the function is defined
In f(x) there is no restriction for x. the function is defined for all x values
so domain is (-∞,∞)

The domain is the set of x values for which the function is defined
when x=0, e^0=1 that makes the denominator 0
Denominator 0 is undefined. So x cannot be 0
domain is (-∞,0) U(0,∞)
Answer: 6.28 feet
Step-by-step explanation:
Area of the lens= πr^2
Since area has been given as 3.14
3.14 = πr^2
Note that π = 3.14
3.14 = 3.14r^2
r^2 = 3.14/3.14
r^2 = 1
r = ✓1
r = 1
The radius of the lens is 1
Circumference of the lens= 2πr
= 2 × 3.14 × 1
= 6.28 feet
