Need help for mathematics 25 points and brainliest

To find the y-intercept, would I just make x = 0?

E.g. for a)

y = x² + 3

y = 0² + 3

y = 3

So would the Y intercept be 3?


Final Question - How would I determine if the parabola has 0, 1, or 2 x-intercepts from the graph?

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,

[tex]a {x}^{2} + bx + c[/tex]

We can use the discriminant formula

[tex] {b}^{2} - 4ac[/tex]

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.
