Part 2: Solve a real-world problem using a square root function. When Isabel began her book-selling business, she stored her inventory in her garage.
Now that her
business has grown, she wants to rent warehouse space. Lisa owns a large warehouse nearby and can
rent space to Isabel. The area of the warehouse is 8,100 square feet. Lisa is willing to rent Isabel as little
as 100 square feet of the space or up to as much as the entire warehouse. Her only requirement is that
all spaces must be square.
4
The total length of each row of bookshelves will be
L
of the length of the storage space.
a)
Let x be the area of the space that Isabel rents and f(x) represent the total length of a row of
bookshelves. How would you find the length of a row of bookshelves? (3 points)
O
b Write a function that expresses f(x). (10 points)

c is the answer

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
