Answer:
The value of f(3) is 1.
Step-by-step explanation:
In the graph of f(x),
The input values of f is along x-axis and output value is along y-axis,
In other words,
(x, y) ∈ f
Since, by the graph,
f(x) is passes through the point (3, 1),
i.e. for the input value 3, f gives the output value 1,
⇒ f(3) = 1
Hence, the value of f(3) is 1.
