Answer:
b and c
Step-by-step explanation:
We are given that a population whose growth over a given time period can be described by the exponential model
Let initial population = when time t=0
After integrating
We get ln N=rt +C
Where C is integration constant
When t=0 then N=
Substitute the value of C then we get
When r=0.1 then we get
Hence, the population increase not decrease.
When r= 0
Then we get
Hence, the population do not increase or decrease.
So, a population with r of 0 will have no births or deaths during the time period under consideration.
If we take a positive value of r then the population will increase exponentially .
Hence, option b and c are both correct.
Answer:
Step-by-step explanation:
By definition, a relation is a function if and only if each input value have only one output value.
It is important to remember that the input values are the values of "x" and the output values are the values of "y".
Observe in the graph given in the exercise that the function f(x) is linear.
So, indicates that the input value (x-value) is:
In order to find its output value you can draw a vertical line from to the line and, when it touches the line, you must draw an horizontal line to the y-axis (Observe the picture attached).
Therefore, you can identify that the output value for is:
Then:
