For
to be continuous at
, you need to have the limit from either side as
to be the same.
If
and
, then the limit from the right would be
, so the answer to part (1) is no, the function would not be continuous under those conditions.
This basically answers part (2). For the function to be continuous, you need to satisfy the relation
.
Part (c) is done similarly to part (1). This time, you need to limits from either side as
to match. You have
So,
and
have to satisfy the relation
, or
.
Part (4) is done by solving the system of equations above for
and
. I'll leave that to you, as well as part (5) since that's just drawing your findings.
Answer:
The correct option is;
B. Use a formula
Step-by-step explanation:
Given that Jim and Lillian have the dimensions of the wall they want to paint, therefore, in order to know how much paint they need to buy, they should proceed as follows;
1) Determine the quantity of paint required to paint a unit area of the wall, and record the quantity UA
2) Calculate the area, A, of the wall they want to paint, which is 15 ft. × 9 ft. = 135 ft.²
3) The amount of paint needed, AmP is therefore given by the following formula
AmP = A × AU = 135 × AU
