The answer is D(same slope and diff intercepts are the key to having parallel lines)
Answer:
Relation
Explanation:
The definition of a relation is just a set of ordered pairs.
A function is a relation in which each domain element is paired with exactly one range element.
It can't be a function because if it is a vertical line, then the x-value is the same for the whole line.
I hope that helps a bit
<u>Answer:</u>
f(x) = 7 is an even function.
<u>Step-by-step explanation:</u>
Any function is even when 
and gives a graph that is symmetric with respect to the y-axis.
We are given these options and we have to check whether which of them is an even function:
and 
- This function is not even
and 
- This function is not even
and 
- This function is not even
and 
- EVEN FUNCTION
We get the same value for 
and 
, therefore f(x) = 7 is an even function.
X = 12400
20/100 = 1/5
2480 x 5 = 12400
