What is the axis of symmetry in a parabola?
Back
The axis of symmetry is a vertical line that divides the parabola into two equal halves. It passes through the vertex of the parabola.

FLASHCARD QUESTION
Front
Where is the vertex of a parabola located?
Back
The vertex is the highest or lowest point of the parabola, depending on its orientation. For example, in the vertex form y = a(x-h)² + k, the vertex is at the point (h, k).

What are the solutions of a quadratic equation?
Back
The solutions of a quadratic equation are the values of x that make the equation equal to zero. They can be found using factoring, completing the square, or the quadratic formula.

FLASHCARD QUESTION
Front
What is the y-intercept of a parabola?
Back
The y-intercept is the point where the parabola intersects the y-axis. It can be found by setting x = 0 in the equation of the parabola.

FLASHCARD QUESTION
Front
How do you find the vertex of a parabola given its equation in standard form?
Back
For a parabola in standard form y = ax² + bx + c, the vertex can be found using the formula x = -b/(2a) and then substituting this x-value back into the equation to find the y-coordinate.

FLASHCARD QUESTION
Front
What does the term 'concave up' mean in relation to a parabola?
Back
A parabola is concave up if it opens upwards, meaning the vertex is the minimum point. This occurs when the coefficient 'a' in the equation y = ax² + bx + c is positive.
