Why is it so quiet? I can't hear it with my speakers turned right up.

If I have the quadratic x^2 - 4 would the vertex be found on the left or right of the y axis? Just getting confused with two sources telling me different things :D

@12308madman Hey Madman. For a quadratic that does not have a "middle" term, the vertex is always ON the y-axis. Think of x^2 - 4 as x^2 + 0x - 4. Then, if you follow my video, a = 1, b = 0, c = -4. Plug in the a, b, and c values into the formula in the video. Since the b-value is always zero, the vertex is always on the y-axis. I hope that helped! Good luck.
