i need help with d and e

Transcribed Image Text:Consider the set V of all real triples of the form \((a, b, c)\) where \(c = a - 2b\) under the usual vector addition and scalar multiplication of \(\mathbb{R}^3\). This same candidate for a Vector Space (or Subspace of \(\mathbb{R}^3\)) is used in the next question.
Give the following (fill in the blanks) examples of 3-tuples in V as requested. **Write your answers as comma-delimited triples using parentheses. For ease in reading, place a space after each comma. If no such requested element exists, write the word "none" in the box (no quotation marks).**
a. a specific element of V whose first and third components are the same:
\(\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\)
b. a specific element of V whose third component is 6.
\(\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\)
c. a non-zero specific element of V whose second component is -1.
\(\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\)
d. a specific element of \(\mathbb{R}^3\) that is not in V.
\(\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\)
e. a specific element of V in V for which \(-v\) is not in V.
\(\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\)
