Answer:
D. Both B and C.
Step-by-step explanation:
For an ordered pair relation to represent a function, then none of the first coordinate must repeat.
In other words, no two or more ordered pairs should have the same first coordinate.
For options A, the first coordinate repeated.
For options B and C, none of the first coordinates repeat.
Both represent a function.
The correct choice is D
Answer:
Step-by-step explanation:
By looking at the graph I notice an open circle at (-4, -5) which means the function is not evaluable at -4, this restricts the domain.
The Domain of a function represents the set of values for which the function has an output.
The Range of a function is the set containing all the possible values associated with all input.
Domain in interval notation: (-4, 3]. The parenthesis denotes that the interval does not contain the extreme point -4. The brackets are the opposite.
Domain in set builder notation:
Range in interval notation: (-5, -3]
Range in set builder notation:
After x years the value (V) is:
<span>Original - 4000x </span>
<span>so, after 3 years we have: </span>
<span>Original - 12000 = 18000 </span>
<span>b: Original = $30,000 </span>
