Answer:
The function has a y-intercept of (0,-1).
Explanation:
The given function is f(x) = x - 1 .......... (1) 
Now, we have to choose from the statements given in options that best describe the function. 
I think option 3 is the only statement that describes the function well. 
Option 3 states that the function has a y-intercept of (0,-1). 
If we put x = 0 in the function then will get y = - 1. 
So, the function (1) has y-intercept at (0,-1). (Answer)
