Does this image represent a function?
1 answer:
Answer:
The given image represents a function
Step-by-step explanation:
If you plot the given inputs and outputs on a graph, it's easier to see whether the given relation is a function.
The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places <u><em>at exactly one point</em></u>, then the relation is a function.
Plotting the points of the given relation on a graph shows that there is only 1 point for each of the vertical lines (in purple) drawn on the graph. This means that the given relation passed the vertical line test, indicative of a function.

<em><u>Question:</u></em>
Which of the following is another way to express the equation 8 - (-d) = 43?
A.8-d=43
B.-d+8=43
C.-8+d=43
D.8+d=43
<em><u>Answer:</u></em>
8 + d = 43 is another way to express the given equation
<em><u>Solution:</u></em>
Consider the given equation
We have to find the another way to express the above equation
We know that,
We we multiply negative sign number by another negative sign number, then the result is positive sign number
Therefore from given,
<em><u>Thus the given equation becomes,</u></em>
8 + d = 43
Thus option D is correct
