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.
Answer:
2, 4.5 and 8
Step-by-step explanation:
(1)
The mode is the number which occurs most often , then
mode = 2
(2)
The median is the middle value of the numbers arranged in ascending order. If there is no exact middle value then it is the average of the numbers either side of the middle.
1, 2, 2, 3, 4, 5, 6, 7, 8, 9
↑ middle
median = =
= 4.5
(3)
The range is the difference between the largest and smallest values
range = 9 - 1 = 8
