Step-by-step explanation:
Yes, the y intercept is 3.
To determine the number of x intercepts, use the discriminant formula.
For a quadratic equation,

We can use the discriminant formula

To find the types of x intercepts,
If our answer is Positve, we have two x intercepts
If our answer is zero, we have one x intercepts
If our answer is negative, we have no x intercepts.
