Identify parts of a parabola

Front

What is the axis of symmetry in a parabola?

Back

The axis of symmetry is a vertical line that passes through the vertex of the parabola, dividing it into two mirror-image halves.

Front

Where does the axis of symmetry line pass through?

Back

The vertex.

Front

What is the vertex of a parabola?

Back

The highest or lowest point of a parabola.

Front

What does the minimum of a function represent in a parabola?

Back

The minimum value is the lowest point on the graph of the parabola.

Front

How many zeros can a parabola have?

Back

A parabola can have 0, 1, or 2 zeros (x-intercepts).

Front

What is a y-intercept?

Back

The y-intercept is the point where the parabola crosses the y-axis.

Front

How do you find the y-intercept of a parabola?

Back

Set x = 0 in the equation of the parabola and solve for y.

Front

What is the standard form of a parabola's equation?

Back

The standard form is y = ax^2 + bx + c.

Front

What does the 'a' value in the parabola's equation indicate?

Back

The 'a' value determines the direction of the parabola (upward if a > 0, downward if a < 0) and its width.

Front

What is the significance of the 'b' value in the parabola's equation?

Back

The 'b' value affects the position of the vertex along the x-axis.
