The relation is not a function.
Step-by-step explanation:
By definition, a relation is a function if each input value has only one output value.
Given the relation:
(4,23)
(3,-2)
(-6,5)
(4,6)
The domain is the set of the x-coordinates of each ordered pair (You do not need to write 4 twice):
{}
The range is the set of the y-coordinates of each ordered pair :
{}
Since the input value 4 has two different output values (23 and 6), the relation is not a function.

- Addition (+) and subtraction (-) round by the least number of decimals.
- Multiplication (* or ×) and division (/ or ÷) round by the least number of significant figures.
- Logarithm (log, ln) uses the input's number of significant figures as the result's number of decimals.
- Antilogarithm (n^x.y) uses the power's number of decimals (mantissa) as the result's number of significant figures.
- Exponentiation (n^x) only rounds by the significant figures in the base.
- To count trailing zeros, add a decimal point at the end (e.g. 1000.) or use scientific notation (e.g. 1.000 × 10^3 or 1.000e3).
- Zeros have all their digits counted as significant (e.g. 0 = 1, 0.00 = 3).
- Rounds when required, after parentheses, and on the final step.

Answer:
a) False
b) False
c) True
d) False
e) False
Step-by-step explanation:
a. A single vector by itself is linearly dependent. False
If v = 0 then the only scalar c such that cv = 0 is c = 0. Hence, 1vl is linearly independent. A set consisting of a single vector v is linearly dependent if and only if v = 0. Therefore, only a single zero vector is linearly dependent, while any set consisting of a single nonzero vector is linearly independent.
b. If H= Span{b1,....bp}, then {b1,...bp} is a basis for H. False
A sets forms a basis for vector space, only if it is linearly independent and spans the space. The fact that it is a spanning set alone is not sufficient enough to form a basis.
c. The columns of an invertible n × n matrix form a basis for Rⁿ. True
If a matrix is invertible, then its columns are linearly independent and every row has a pivot element. The columns, can therefore, form a basis for Rⁿ.
d. In some cases, the linear dependence relations among the columns of a matrix can be affected by certain elementary row operations on the matrix. False
Row operations can not affect linear dependence among the columns of a matrix.
e. A basis is a spanning set that is as large as possible. False
A basis is not a large spanning set. A basis is the smallest spanning set.
Answer:
1.) $640 2.) 7 years.
Step-by-step explanation:
1000 x .2 = 200 1 yr
1000 - 200 = 800
800 x .2 = 160 2 yrs
800 - 160 = 640
640 x .2 = 128 3 yrs
640 - 128 = 512
ANYWAYS THIS WOULD TAKE TO LONG! SO HERE IS THE ANSWER TO B.
