How do you identify decreasing intervals on a graph?

Back

Look for sections of the graph where the slope is negative, indicating that as x increases, y decreases.

Front

What does it mean if a quadratic equation has no real solution?

Back

It means the discriminant (b^2 - 4ac) is less than zero, indicating that the parabola does not intersect the x-axis.

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation (upward or downward).
