Question

If the point (9, 8) is on the graph of f, then f(9) =

Answer 1

The value of the function f at x equals 9, denoted as f(9), is 8, since the point (9, 8) lies on the graph of the function f.

Step-by-step explanation:

If the point (9, 8) is on the graph of f, then f(9) = 8. The notation f(9) represents the value of the function f at x = 9.

Each point on the graph of a function is an ordered pair (x, y) where the first element is the input to the function, and the second element is the output.

Since (9, 8) lies on the graph, the output when the input is 9 is 8, meaning f(9) equals 8.
