Which representation of a function more clearly shows whether or not the function is linear: a table of values or a graph? Explain.
Answer to Problem 3C
A graph shows more clearly that a function is linear.
Explanation of Solution
A graph is a visual representation and table of values is a theoretical representation.
We know that graph of a linear function is a straight line. We can easily identify a linear function from its graph.
We know that visual representation is more effective than theoretical representation. Therefore, agraph shows more clearly that a function is linear or not.
