Answer:
4 · 1/4 (I-0) = (A-0)∧2
see details in the graph
Step-by-step explanation:
Matrix A is expressed in the form A∧2=I
To proof that Matrix A is both orthogonal and involutory, if and only if A is symmetric is shown by re-expressing that
A∧2=I in the standard form
4 · 1/4 (I-0) = (A-0)∧2
Re-expressing
A∧2 = I as a graphical element plotted on the graph
X∧2=I
The orthogonality is shown in the graphical plot displayed in the picture. Orthogonality expresses the mutually independent form of two vectors expressed in their perpendicularity.
Answer:
C. .
Step-by-step explanation:
The domain of the function refers to the values of for which the function is defined.
We can see from the graph that, the function is defined within the interval,
.
When we trace any x-value outside this interval, either up or down we will not meet the function.
Hence, the domain is .
