Answer 1

Answer:

The option (A) is correct that is f(1) =0 .

Step-by-step explanation:

We can see from the given graph that it is step function

and also interpret as :

value of function at value of  x are:

at x= 1 is f(1) =0

at x=2 is  f(1) =1

at x=4 is  f(1) =2

at x= -2 is  f(1) = -1

at x= -4 is  f(1) = -2

Hence, the option (A) is correct that is f(1) =0 .
