Step-by-step explanation:
f(x) = 9 * 81^x
When x = -1/2,
f(-1/2) = 9 * 81^(-1/2) = 9 * (1/9) = 1.
The slope should be one over two.
Answer:
It should be -5/2 for the points (-6,8) (-16,33)
Step-by-step explanation:
For this case we have a function of the form
Where:

We must find the value of the function when the variable x is -5.
Then, substituting, 

We have that by sign law
