Answer:

Step-by-step explanation:
Given the function:

To find:
Domain of the function.
Solution:
First of all, let us learn about definition of domain of a function.
Domain of a function is the valid input values that can be provided to the function for which output is defined.
OR
Domain of a function
are the values of
for which the output
is a valid value.
i.e. The function does not tend to
or does not have
form.
So, we will check for the values of
for which
is not defined.
For value to tend to
, denominator will be 0.

So, the domain can not have x = 2
Any other value of x does not have any undefined value for the function
.
Hence, the answer is:
[2 is not included in the domain].
Is where the line is horizontal
1 =< x <= 6
Its B
447/250
is the answer to the question
Answer:
45 or multiples of 45 around the centre of octagon
Step-by-step explanation:
Given that ABCDEFGH is a regular octagon. i.e. it has 8 sides.
Since regular ocagon, all interior angles would be equal.
Sum of all interior angles of octagon = 2(8)-4 right angles
= 12 right angles
Hence each angle = 12(90)/8 = 135 degrees
Thus the octagon when rotated will take the same shape if vertices interchange also due to the property that all sides and angles are equal
Since each angle is 135 imagine an octagon with one vertex at origin O, and adjacent vertex B on x axis. OB has to be coincident with BC the next side or the previous side to get it mapped onto itself
The centre will be at the middle with each side subtending an angle of 45 degrees.
Hence if rotation is done around the centre with 45 degrees we will get octagon mapped onto itself.
45, 90, 135 thus multiples of 45
