Answer:
The option (A) is correct that is<u> f(1) =0</u> .
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<u> f(1) =0</u> .
