Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
Question
For this week's discussion, you are asked to generate a continuous and differentiable function f(x) with the following properties:
- f(x) is decreasing at x=−5
- f(x) has a
local minimum at x=−3 - f(x) has a
local maximum at x=3
Hints:
- Use calculus!
- Before specifying a function f(x), first determine requirements for its derivative f′(x). For example, one of the requirements is that f′(−3)=0 .
- If you want to find a function g(x) such that g(−9)=0 and g(8)=0, then you could try g(x)=(x+9)(x−8).
- If you have a possible function for f′(x), then use the techniques in Indefinite Integrals this Module to try a possible f(x).
Please note that the bounds on the x-axis go from -6 to 6.
