Answer:
The y-intercept is y = 2
Step-by-step explanation:
A linear function has the following format:

In which m is the slope and b is the y-intercept, which is the value of y when x = 0.
We are given these three points:
(-28, -54)
(-21, -40)
(-14, -26)
We use two of them to build a system, to find values for m and b.
(-28, -54)
This means that when 
So




(-21, -40)
This means that when 
So








The y-intercept is y = 2
Answer:
119
Step-by-step explanation:
it will be the same as 8 because they are adjacent..
Answer:
the answer is c = (ad)/b
Step-by-step explanation:
See the picture
Answer:
See explanation
Step-by-step explanation:
You are given the function 
The domain of the function are all possible values of variable x, so you can find f(x) for x=-2, 0, 3, 5:

The table is

The inverse function
has the domain which is the range of the function f(x) (all possible values of f(x)), so the domain of inverse function is {-7,-1,8,14}
