FLASHCARD QUESTION
Front
How do you find the maximum height of a projectile from a quadratic graph?
Back
The maximum height can be found at the vertex of the parabola, which can be calculated using the formula x = -b/(2a) from the quadratic equation ax² + bx + c.

FLASHCARD QUESTION
Front
What does the x-intercept of a quadratic graph represent?
Back
The x-intercepts of a quadratic graph represent the points where the graph crosses the x-axis, indicating the values of x for which the quadratic function equals zero.

FLASHCARD QUESTION
Front
What does the y-intercept of a quadratic graph represent?
Back
The y-intercept of a quadratic graph is the point where the graph crosses the y-axis, representing the value of the function when x = 0.

FLASHCARD QUESTION
Front
How can you determine the time it takes for a projectile to reach its maximum height from a quadratic graph?
Back
The time to reach maximum height can be found by locating the vertex of the parabola on the time (x) axis.

FLASHCARD QUESTION
Front
What is the significance of the axis of symmetry in a quadratic graph?
Back
The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves. It passes through the vertex and can be found using the formula x = -b/(2a).
