Answer:
f(1) = 2
Step-by-step explanation:
Since y is a function of x, that is;
y = f(x)
f(1) implies the value of y when x = 1.
To obtain this value we draw the vertical line x = 1 and check where the line intersects the graph of f(x).
In this case, the line x = 1 will intersect with the graph of f(x) on the line y = 2. The function f(x) assumes the value 2 between x = 0 and x = 4. Therefore,
f(1) = 2
