ANSWER
The correct answer is

EXPLANATION
The mapping for reflection across the x-axis is given by

Given

. We can let

we can write the ordered pair

or

as the ordered pair of the preimage of

.
The image function will have the ordered pair

or

.
That is, we negate all the y-coordinates.
Therefore

.
Answer:
Therefore surface integral is
.
Step-by-step explanation:
Given function is,

To find,
where S=A=surfece of elliptic cylinder we have to apply Divergence theorem so that,





- If unit vector
directed in positive (outward) direction then z=c and,

- If unit vector
directed in negative (inward) direction then z=-c and,

Therefore surface integral without unit vector of the surface is,

Making a table helps compare two or more sets of data because you can see how much it has increased or decreased.
