Answer:
f-¹(x) = 2x – 8
f-¹(4) = 2(4) – 8 —> f-¹(4)= 8 - 8 =0

The area of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width.
Then, you can notice that it can be obtained by multiplying the dimensions of the rectangle.
Knowing this, you can determine that the total area of the two flowers bed can be obtained by adding the products of their dimensions.
Since one of the rectangular flower bed is 2.78 feet by 4.81 feet and the other bed 2.78 feet by 5.61 feet, you can write the following expression to find the total area (in square feet)of the two beds:
If you factor out 2.78:
or 
Therefore, the expression that does not represent the total area in square feet of the two beds, is:
Answer:
Quadratic functions are those where their rate of change changes at a constant rate. Exponential functions are those where their rate of change is proportional to itself.
An example of a quadratic function would be the shape that a ball makes when you throw it. Gravity causes a constant acceleration, the ball slows down as it is moving up, and then it speeds up as it comes down.
An example of an exponential function would be the population of a bacterium as long as there is enough space and nutrients or how your money grows with compound interest in a bank.
A quadratic function is one in the form
f(x)=ax2+bx+c
It’s rate of change (first derivative) is linear.
f′(x)=2ax+b
The rate of the rate of change (second derivative) is constant.
f′′(x)=2a
Quadratics are then the solutions to the differential equation
f′′=C
An exponential function is one in the following form.
g(x)=Aekx
It’s rate of change is another exponential function.
g′(x)=Akekx
So exponentials are the solutions to the differential equation
g′=kg

Answer:
Andrew purchased 12 pens.
Step-by-step explanation:
First, subtract 5.72 from 20 to get $14.28. Then, divide that by 1.19 to get 12. So, Andrew purchased 12 pens.
