Understanding the y-Intercept

1.Definition: The y-intercept is the point where a graph intersects the y-axis, meaning the x-coordinate is always 0.

2.Given Information: From the graph, we can see that this is a downward-opening parabola that intersects the y-axis at (0, -1). The point (1, 4) is identified as the maximum point of the parabola.

3.Identifying the y-Intercept:

To find the y-intercept, we set x = 0 in the equation of the parabola.

This gives us a y-value of -1, confirming that the y-intercept is at (0, -1).
