According to the problem, y = f(x) = 2x

Here the value of x = 2.

We have to put the value of x in place of x in 2x to calculate the actual value of 2x.

Therefore, after putting the value of x in 2x we get 2x = 2 x 2 = 4

This means the value of 2x is 4. This is because we have included the given value of x to get the value of 2x.

Again the value of f(x) = 2x.

Therefore, the value of f(x) = 2x = 4.

Answer: After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.

Step-by-step explanation:

Given: Sharon is conducting research on two species of birds at a bird sanctuary.

The number of birds of species A is represented by the equation below,where S represents the number of birds, x years after beginning her research.

$S=2^x+12$

The number of birds of species B is represented by the equation below,where S represents the number of birds, x years after beginning her research.

$S=15x+35$

To plot the above function, first find points by which they are passing.

For species A, At x=0 , $S=1+12=13$

At x=2 , $S=2+12=14$

Similarly find more points and plot curve on graph.

For species A, At x=0 , $S=0+35=35$

At x=2 , $S=15+35=50$

Plot a line with the help of these two points.

Now, from the graph the intersection of curve (for A) and line (for B) is at (7,140) which tells that After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.
