For the answer to the question above asking the <span>function f(x) best models the data? The f(x) models are not given but to answer this question</span> just convert the given from meter to kilometer by dividing the number by 1000. this is because 1000 meters is equal to 1 kilometers. The answer is 0.1 km
The negative reference is -0.5235
Answer:
1st choice
Step-by-step explanation:
Temp at noon was -0.6. It increases 1.2 until 3.
-0.6+1.2
gets colder 0.4, then 0.6.
-0.6+1.2-0.4-0.6
the only correct way to put this equation as one of the other answers is by putting it as -0.6+1.2+(-0.4)+(-0.6)
hope that helped!
Answer:
-15
Step-by-step explanation: the only numbers that can be used under a 0 is negative and since its colder it goes down -15+0 is -15

Answer: Choice C</h3>
Why isn't choice C a function? It's because we have the input x = 4 lead to more than one output at the same time (y = 5 and y = -5). A function must have all allowed inputs lead to exactly one output.
The diagram for choice C shows we have the points (4,5) and (4,-5). If we plotted those two points, then a vertical line forms, which will show this relation fails the vertical line test.
Choices A, B, and D do not have this happen where a certain input leads to multiple outputs at once; therefore, these are all functions. For the tables A and D, note there aren't any repeated x values. If you were to convert choice C into table form, then you would have the x value 4 repeat itself.
