Question

Which is true regarding the graphed function f(x)?

Answer 1

F(5)=-1

Thats it.................

Answer 2

Answer: Second option.

Explanation:

By definition, a relation is a function if for each input value (value of x) there is an unique output value (value of y).

1) For
`f(0)=3` the input value is
`x=0` and the output value is
`y=3`, obtaining the point (0,3) which is not true for the function f(x) shown in the graph.

2) For
`f(5)=-1` the input value is
`x=5` and the output value is
`y=-1`, obtaining the point (5,-1) which is true for the function f(x) shown in the graph.

3) For
`f(3)=2` the input value is
`x=3` and the output value is
`y=2`, obtaining the point (3,2) which is not true for the function f(x) shown in the graph.

4) For
`f(2)=-2` the input value is
`x=2` and the output value is
`y=-2`, obtaining the point (2,-2) which is not true for the function f(x) shown in the graph.
