Step-by-step explanation:
definition of the derivative to differentiate functions. This tutorial is well understood if used with the difference quotient .
The derivative f ' of function f is defined ascthe above pic.
when this limit exists. Hence, to find the derivative from its definition, we need to find the limit of the difference quotient.
Answer:
(A)
Step-by-step explanation:
Let y be the length of the rectangular backyard and then according to the question, y should be atleast 150 ft, then the possible inequality is:
and the distance around should be no more than 450ft, then the possible inequality is:
Then, the shaded region (green) is the possible dimensions of the backyard.
