Answer:
Step-by-step explanation:
The given quadratic form is of the form
.
Where .Every quadratic form of this kind can be written as
Observe that is a symmetric matrix. So is orthogonally diagonalizable, that is to say, where is an orthogonal matrix and is a diagonal matrix.
In our case we have:
The eigenvalues of are .
Every symmetric matriz is orthogonally diagonalizable. Applying the process of diagonalization by an orthogonal matrix we have that:
Now, we have to do the change of variables to obtain
Which can be written as:
Answer:
The domain of this function is [0, infinity ).
Step-by-step explanation:
Here the y-axis is the vertical asymptote. We can therefore deduce that x may never be zero or negative. The domain of this function is [0, infinity ).
Answer:
irrational
Step-by-step explanation:
that is..... if it keeps in continuing forever
