What is the vertex of a parabola?

Back

Front

Back

The vertex can be found directly from the equation in vertex form. Here, the vertex is (3, 4).

What does it mean for a parabola to have zeros?

Back

Zeros of a parabola are the x-values where the graph intersects the x-axis. The number of zeros indicates how many times the parabola crosses the x-axis.

Front

Back

This parabola has 2 zeros, which can be found by factoring or using the quadratic formula.

What is the significance of the ordered pair (0, -2) in a graph?

Back

The ordered pair (0, -2) represents the y-intercept of the graph, which is the point where the graph crosses the y-axis.

Front

How do you factor the quadratic expression 3a^2 + 4a + 1?

Back

The expression can be factored as (3a + 1)(a + 1).

Front

What is the difference between a maximum and minimum vertex?

Back

A maximum vertex is the highest point of a downward-opening parabola, while a minimum vertex is the lowest point of an upward-opening parabola.

Front

What is the general shape of a parabola?

Back

A parabola is a U-shaped curve that can open upwards or downwards, depending on the sign of the leading coefficient (a) in the quadratic equation.
