Explanation:
The function is given below as
The set of domains is given below as
Step 1:
Put x=-1
Step 2:
Put x=0
Step 3:
Put x=1
Step 4:
Put x=2
Hence,
The range of g(x) using set notation will be
Hence,
The graph of g(x) is given below as
Circular pen means you are going to use Area = Pi(r^2).
So 78.5 = pi(r^2). Divide by pi on both sides to get r^2 = 78.5/pi. Take the square root of that to get r or radius = approximately 4.99. If you need an exact answer then use
for the next part because you are not done yet.
Plug whatever R you use into the circumference formula of Circumference = 2(pi)(r).
If you use 4.99, you do 2(pi)(4.99) which is approximately 31.35. If you use the exact answer, you do 2(pi)(
) which gives you approximately 31.41.
Either way you'll need about 31 meters of chicken wire but the 31.40796 or ~31.41 is closer to the exact answer.
