Answer:
- the domain is [0,129]
- 112 mm
- 1942
Step-by-step explanation:
1. The function is good for years 1880 to 2009, 0 to 129 years after 1880. Values of x can be anything in the domain [0, 129].
__
2. 1950 -1880 = 70. The year 1950 corresponds to x=70, so the function tells us the water level rose ...
f(70) = 1.6·70 = 112 . . . . . mm
__
3. We want to find x when f(x) = 100. That will be the solution to ...
100 = 1.6x
100/1.6 = x = 62.5
Then 62.5 years after 1880 is year 1942.5. The water level was 100 mm higher than in 1880 in the year 1942.
The answer is (-2,3)
hope you have a great day ;)

a = 5
b = -3
25 - -3/ -3 - 25
= 28 / -28
= -1
Answer:
the 3rd one
Step-by-step explanation:
Answer:
No, because it doesn't pass the vertical line test. There are two y's for every x. Therefore, it is not a function
Answer: Option B, The graph does NOT represent a function
