Question

13 what is the domain of the function? (a) graph of a function with points at (4, y), (8, y), (12, y) domain: { i____ } {4, 8, 12} ×

Explanation:

Step1: Identify x - values of points

The graph has points at \((4, y_1)\), \((8, y_2)\), and \((12, y_3)\). The domain of a function is the set of all x - values of the ordered pairs \((x,y)\) that belong to the function.

Step2: List the x - values

The x - values of the given points are 4, 8, and 12. So we list these values in the set for the domain.

Answer:

\(\{4, 8, 12\}\)
