Graphed Functions
When we are finding f(x) given a value of x, we must identify the value of y that results from the value of x.
Solving the Question
We are asked to find f(2).
On the graph, first find the location of x=2.
Then, identify where the function is at x=2.
Finally, identify the corresponding y-value: 12.
Answer
The value of f(2) is 12.
