We have a single y-intercept at (0, -3). The correct option is B.
How to find the y-intercept of tha parabola?
The y-intercept is the point at which the graph intercepts the vertical axis, so we just need to identify the y-value at which this happens.
We can see that the parabola intercepts the y-axis at y = -3 (and trivially in the y-axis the value of x is always zero)
Then the y-intercept is only one point and is at (0, -3)
