The graph shows a parabola opening upwards, and you're asked to find the y-intercept.

The y-intercept of a graph is the point where the curve crosses the y-axis. For a parabola, this occurs when $x = 0$.

Looking at the graph, the curve crosses the y-axis at $y = -10$.

Thus, the y-intercept is:

$y = -10$
