Answer:
Here is the complete question (attachment).
The function which represent the given points are
Step-by-step explanation:
We know that a general exponential function is like,
We can find the answer by hit and trial method by plugging the values of coordinates.
Here we are going to solve this with the above general formula.
So as the points are then for
Can be arranged in terms of the general equation.
...equation(1) and
...equation(2)
Plugging the values in equation 2.
We have
Plugging in equation 1.
We have
Comparing with the general equation of exponential and
So the function which depicts the above points =
From theoption we have B as the correct answer.
