This question is solved applying the formula of the area of the rectangle, and finding it's width. To do this, we solve a quadratic equation, and we get that the cardboard has a width of 1.5 feet.
Area of a rectangle:
The area of rectangle of length l and width w is given by:
w(2w + 3) = 9
From this, we get that:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that
, given by the following formulas:
In this question:
Thus a quadratic equation with
Then

Answer:
<u>Question 1</u>
The function is one-to-one, so it does have an inverse.
The inverse of +6 is -6, so
Therefore, g(x) is the inverse of f(x).
<u>Question 2</u>
The function is one-to-one, so it does have an inverse.
To find the inverse, replace f(x) with y:
Rearrange the equation to make x the subject:
Replace x with and y with x:
Therefore, g(x) is the inverse of f(x).
