IM STUCK ! how do I determine the zeros if my x intercepts from the quadratic formula is this ! (in the picture) what do I do to find the y intercept ?!

The y-intercept is -3, but consider that 'a' is 4 and not 1, in your solving. Hope, I helped you.

Step-by-step explanation:

First, let's solve the quadratic equation given, and find the x-intercepts:

Using the quadratic equation:

But note that:

So,

Zeros/Roots:

The y-intercept is when x is equal to 0, so:

answer: 10 meter
