Answer:
The rate of decay is 0.08
Step-by-step explanation:
we have
Let
r-----> the rate of decay
we know that
In this problem
Solve for r
Given:
The points are (-3, 2) and (2, -13).
To find:
Slope-intercept form of the equation.
Solution:
Here .
Slope of the line:
m = -3
Using point-slope formula:
Add 2 on both sides.
Slope-intercept form of the equation is y = -3x - 7.
the first is a linear
second is an exponential
third is quadratic
