I believe it is a but i will double check and post ok
The answer is -|0.35 t -14| +14
<u>Step-by-step explanation</u>:
The problem statement is asking for an expression for distance in miles, so the constants in the expression will be miles. In the time it takes to get to point B (40 minutes), the ferry has gone (0.35 mi/min)×(40 min) = 14 mi. Hence the maximum value of the function must be 14. The only function with that characteristic is the one of selection D.
Step-by-step explanation:
To find the y-coordinate points we need to evaluate the function for all the
values in the table. In other words, we need to replace
with each value in our given function and simplify.
- For x = 0





Since
and
, our first point is (0, -1)
- For x = 1





Our second point is (1, -4)
- For x = 2




Our third point is (2, -5)
- For x = 3





Our fourth point is (3, -4)
- For x = 4





Our fifth point is (4, -1)
Now we just need to plot each point in our coordinate plane and join them with the parabola as you can see in the attached picture.
Answer:
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
