Answer:
(A) Scatterplot
Step-by-step explanation:
The most helpful visualization to spot outliers would be a scatterplot.
When collecting data on a scatterplot, you can see how the results are similar and which areas have the most answers and such.
There can be multiply outliers on a scatterplot, and they stand out because while most answers will be clumped together, the outliers will not.
The solutions to f(x) = g(x) are where the x-values for which the output f(x) is equal to the output of g(x).
What I mean by this is for instance, you input 7 into f(x) and g(x) and you get the same answer, then 7 is a solution.
Here, we are looking in columns two and three to see which rows are equal. It looks like when you input 0 into both f(x) and g(x), you get 2, and when you input 1 into both f(x) and g(x), you get 3.
Therefore, (0,2) and (1,3) are your solutions.
