Matrix index is row then column, so b42 is the fourth row and seconds column of the matrix b. In this case, that is -1.
Answer:
...
Step-by-step explanation:
di = 2.5 -( - 1.5) = 4
radius = di/2 = 2
c(x, y) =( - 0.5 , 2.5-0.5) =(-0.5 , 0.5)
<u>The right answer is:</u> Determine whether
is equivalent to 
A function is said to be even if its graph is symmetric with respect to the
. That is:

According to this definition, the statement that best describes if the function:

is even, is:
Determine whether
is equivalent to 
By doing this, we have:

As you can see:

Conclusion:<em> </em><em>The function is not even.</em>
