The domain is the set of allowed input x values for the function. In this case, the domain is the inequality
x > -8 (note the vertical asymptote at x = -8 in which the function never touches)
If you want to write the domain in interval notation, then you would write
which is the interval from -8 to positive infinity (excluding both endpoints)
Answer:
10 inches by 7 inches
Step-by-step explanation:
Let L and W represent the length and width of the rectangle, in inches. Then L = W + 3.
The perimeter is P = 2L + 2W, or P = 2(W+3) + 2W = 34 inches.
Solving for W: 2W + 6 + 2W = 34 inches, or
4W + 6 = 34 inches, or
4W = 28 inches, or W = 7 inches.
Given that L = W + 3, L = (7 inches) + 3 inches = 10 inches.
The length of the rectangle is 10 inches, and its width is 7 inches.
