The average rate of change of a function, g(x), over an interval [a, b] is given by
Thus, the average rate of change of
over the interval 
is given by:
![Average\ rate\ of\ change= \frac{[-(8)^2-4(8)]-[-(6)^2-4(6)]}{8-6} \\ \\ = \frac{(-64-32)-(-36-24)}{2} = \frac{-96-(-60)}{2} = \frac{-96+60}{2} = \frac{-36}{2} \\ \\ -18](https://tex.z-dn.net/?f=Average%5C%20rate%5C%20of%5C%20change%3D%20%5Cfrac%7B%5B-%288%29%5E2-4%288%29%5D-%5B-%286%29%5E2-4%286%29%5D%7D%7B8-6%7D%20%5C%5C%20%20%5C%5C%20%3D%20%5Cfrac%7B%28-64-32%29-%28-36-24%29%7D%7B2%7D%20%3D%20%5Cfrac%7B-96-%28-60%29%7D%7B2%7D%20%3D%20%5Cfrac%7B-96%2B60%7D%7B2%7D%20%3D%20%5Cfrac%7B-36%7D%7B2%7D%20%20%5C%5C%20%20%5C%5C%20-18)

Answer:
The graph in the attached figure
Step-by-step explanation:
we have
y=x+2.05
This is a linear equation ( equation of a line)
To graph the line find the intercepts
<u>The y-intercept</u> is the value of y when the value of x is equal to zero
For x=0
y=0+2.05=2.5
The y-intercept is the point (0,2.05)
<u>The x-intercept</u> is the value of x when the value of y is equal to zero
For y=0
0=x+2.05
x=-2.05
The x-intercept is the point (-2.05,0)
To graph the line plot the intercepts and then join the points
using graphing tool
see the attached figure
