For something to be a function, the input (x value) can ONLY HAVE ONE output (y value), so if x has multiple outputs, it is not a function
B is not a function because x = 2 and x = 9 has 2 outputs
Your answer is A
Answer: 0.87 times per second (Or 52.2 times per minute)
Step-by-step explanation:
You need to make the conversion from minutes to seconds.
Remember that 1 minute has 60 seconds. Then 20 minutes to seconds is:
Find the number of times the heart beats in 1 second when it is rowing:
Find the number of times the heart beats in 1 second when it is resting:
Then the difference is:
(Or 52.2 times per minute)
So to get the fractions easier to understand you need to put them on the same level you are on. So change the 9/10 gallons to 18/20 ( this makes them easier to deal with the 1/20)
so put 1/20 into 18/20. Liam can paint 18 bird houses.
Answer:
Domain is the values of x within the function and y is the values of y within the function. They are the defined values for x, and y respectively, where the function results in a function. For any function, the domain is the input value and the range is the output values.
Hope this helps :)
