Find a function value from a table using function notation

Problem

Use the table to determine \(f(3)\) and justify the result from the listed inputs.

Answer choices

The table lists inputs 1, 2, and 5, so since x = 3 is not shown, f(3) is not determined from the table.

The number inside f(3) is 3, so f(3) = 3 because the input and output match.

The table shows 8 twice, so f(3) = 8 because 3 should have the same output as the nearby inputs.

Since 3 is not listed among the outputs 8, 8, and 1, f(3) is undefined from the table.
