Answer:
1
Step-by-step explanation:
f(1) is simply the value of f(x) when x = 1. Therefore, looking at the graph, when x = 1, f(x) = 1.
f(1) is the "value of the function f when the input "x" is 1. We look at the diagram and find (or draw) a vertical line through x = 1. At what y value does this line intersect the graph? I see y = f(1) = 1. ( Look for the point (1, 10). )
