Answer:
D: function is positive for all values in the domain
Step-by-step explanation:
When we look at the graph , we can see that
if x approaches ∞ , then y values approaches ∞ (positive)
if x approaches -∞ , then y values approaches 0 (positive)
So for any value of x , the value of y is positive
We know x values are the domain
the y values are positive for all domain (x values)
Hence function is positive for all values in the domain
The answer would be C)3-x/x(x-1)
Answer: 11 1/2 ft
Step-by-step explanation:
We know that the equation for the area of a rectangle is:
length x width = area
All we have to do is fill it in with the numbers and solve:
length x 8 1/3 = 95 5/6
length = 95 5/6 ÷ 8 1/3
length = 23/2 = 11 1/2
Thus, the length of Tamara's room is 11 1/2 feet.
