1. let f(x)=8/1+3e^−0.7x. what is the value of f (−3)? 2. let f(x)=20/1+9e^3x. what is the y-intercept of the graph of f(x)? 3. let f(x)=24/1+3e^−1.3x. what are the asymptotes of the graph of f(x)? 4. let f(x)=15/1+4e^−0.2x. what is the point of maximum growth rate for the logistic function f(x)? 5. let f(x)=24/1+3e^−1.3x. over what interval is the growth rate of the function decreasing?

1. f(x)=8/1+3e^(-0.7x)
to get f(-3) we substitute the value and solve the equation as follows:
f(-3)=8/1+3e^(-0.7*3)
f(-3)=8.36737
which can also be written as:
f(-3)-8.36737=0

2. f(x)=20/1+9e^(3x)
to get the y-intercept we let x=0, hence we shall have:
f(0)=20/1+9e^(3*0)
f(0)=20+9*1
f(0)=20+9
f(0)=29
the y-intercept is at point (0,29)

3. f(x)=24/1+3e^(-1.3x)
Given that the expression above has no denominator, then the domain of the expression is all real numbers then the expression has not vertical asymptote.The same applies for horizontal asymptote and the oblique. 

4. f(x)=15/1+4e^(-0.2x)
 The graph is not increasing at any point, this means that it does not have a point of maximum growth.

5. f(x)=24/1+3e^(-1.3x)
The graph of the function is a decay graph, this means that there is no point in which the graph is increasing hence there's not growth rate.

This meant that state secession was no longer in effect

Explanation:

States i the US had had the natural right of being able to secede from the Union as they had entered it in freewill and not as any forced encounter with the Union itself.

This changed in the Presidential Reconstruction.

This was done away under the 13th amendment after the conclusion of the long bloody war of secession in the Civil war after which it was understood that they must not allow the states to be able to do this anymore.
