Answer:
The relation y=2x+8 is a function because the two different output values of the function have the one unique input value.
Step-by-step explanation:
The given relation is y=2x+8.
It is required to determine the relation is a function.
This solution can be obtained by using the concept of function. First write the given relation y=2x+8 and determine whether the given relation is a function.
Step 1 of 1
The given relation is y=2x+8.
This relation shows that the two different output values of the function have one unique input value and this relation is a linear function.
Hence, the relation is a function.
The initial population was 234.
<em><u>Explanation</u></em>
<u>Formula for the exponential growth</u> is:
, where P is the initial amount, A is the final amount, r is the rate of growth and t is the time duration.
There was 337 bacteria after 5 minutes and 699 bacteria after 15 minutes. So, the equations will be......

Now dividing equation (2) by equation (1) , we will get .......

<u>Taking 'natural log'</u> on both sides.........

Now, plugging this
into equation (1), we will get......

So, the initial population was 234.
30 is the lcm of both the numbers
