Answer:
Step-by-step explanation:
You divide 7.42 / 1.75 = the answer is 4.24
Formula is:
Number of reams per case x number of cases
11 x 12 = 132 reams
f(3) = 1.9
Solution:
Given function:

To find f(3):
Substitute x = 3 in the given function.


Let us first simplify
.
Apply exponent rule: 

The value of
. (using calculator)


Substitute this value in f(3).


f(3) = 1.9
Hence the value of f(3) is 1.9.
