Answer:
Step-by-step explanation:
Given is a function f(x)
![f(x) = e^x -e^{-\frac{{x}}{2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20e%5Ex%20-e%5E%7B-%5Cfrac%7B%7Bx%7D%7D%7B2%7D)
We have to analyse and sketch the graph
X intercept : Put y =0, we get x=0
Y intercept: Put x =0 , we get y =0
No exception for x or y and hence set of all real numbers is domain and range.
![f'(x) = (e^x +1/2 e^{-\frac{{x}}{2})](https://tex.z-dn.net/?f=f%27%28x%29%20%3D%20%28e%5Ex%20%2B1%2F2%20e%5E%7B-%5Cfrac%7B%7Bx%7D%7D%7B2%7D%29)
f' becomes 0 not at finite points
So relative extreme
Graph is sketched and attached
Find the mid point interval for all of the scores and multiply it by it’s respected frequency
10x9
13x29.5
21x49.5
34x69.5
17x89.5
Then add all of the equations together say the answer is x
Then you will go x/94
To get the mean
Answer:
y=-x+8
Step-by-step explanation:
Slope = (y₂-y₁)/(x₂-x₁) = (1-8)/(7-0) = -7/7 = -1
Y-intercept = (0,8)
Therefore, the equation of the trend line is y=-x+8
