Step-by-step explanation:
we know that
The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function
I will analyze two cases
Part 1) we have

so
For x=0
substitute

therefore
The y-intercept is the point (0,0)
Part 2) we have

so
For x=0
substitute

therefore
The y-intercept is the point (0,-1)
