Question

In the graph shown below, what is f(2)?

A. f(2) = 2
B. f(2) = 1
C. f(2) -1 and f(2) = 2
D. f(2) doesn't exist

Answer 1

The answer is A. f(2) = 2

We are looking for where the line is expressed when x = 2. A closed dot allows us to know that point is included. An open dot is not included, although the line approaches it, infinitely closely.

Answer 2

f(2)=2

Explanation:

From the graph we need to find f(2)

f(2) is the value of y when x=2

When x=2 , we have two graphs that goes up and goes down

The down graph starts at y=1 but we have a open circle.

the top graph starts at y=2 but we have closed circle.

to find the value of when x=2, consider the graph with closed circle

So when x=2 the value of y is 2

f(2)=2
