The function f(x) = 2.75x2 models the packaging costs, in cents, for shipping a book with the side lengths, in inches, shown in the diagram. What are reasonable domain and range values for this function? A. domain: 4 ≤ x ≤ 12; range: 6 ≤ f(x) ≤ 18
B. domain: x ≥ 4; range: f(x) ≥ 44
C. domain: 4 ≤ x ≤ 12; range: 44 ≤ f(x) ≤ 396
D. domain: x ≥ 0; range: f(x) > 0

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

4.6875 pounds

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
