Answer:
Domain: (-∞, ∞)
Range: [0, ∞)
Step-by-step explanation:
The domain represents what x can be. In this scenario, we do not have x as a denominator, and there is nothing limiting x, so its domain is (-∞, ∞)
The range represents what f(x) can be, Because |x-4| is in absolute value, the lowest |x-4| can be is 0, and as a result, the lowest value of 2|x-4| is 2*0=0. The maximum value of f(x) is ∞ as an absolute value does not limit the maximum, making the range [0, ∞)
Answer:
i. 6 feet by 3 feet
ii. 7 feet by 2 feet
iii. 8 feet by 1 feet
Step-by-step explanation:
From the given question, we have;
length of the rectangular fence, l = 6 feet
perimeter of the rectangular fence = 18 feet
Let the width of the rectangular fence be represented by w.
So that,
Perimeter of a rectangle= 2(length + width)
18 = 2(6 + w)
18 = 12 + 2w
18 - 12 = 2w
6 = 2w
w = 
w = 3
The width of the rectangular fence would be 3 feet when the length is 6 feet.
Thus, the possible dimensions of the rectangular fence are:
i. 6 feet by 3 feet
ii. 7 feet by 2 feet
iii. 8 feet by 1 feet
