FLASHCARD QUESTION
Front
What is the y-intercept of the quadratic equation y = ax^2 + bx + c?
Back
The y-intercept is the point where the graph intersects the y-axis, which occurs when x = 0. For the equation y = -8x^2 + 3x - 7, the y-intercept is (0, -7).

FLASHCARD QUESTION
Front
Identify the coefficient 'b' in the quadratic function f(x) = ax^2 + bx + c.
Back
The coefficient 'b' is the coefficient of the linear term. In f(x) = 3x^2 + 4x - 5, b = 4.

FLASHCARD QUESTION
Front
How do you find the x-value of the vertex of a quadratic function in standard form?
Back
The x-value of the vertex can be found using the formula x = -b/(2a). For y = 3x^2 - 6x + 4, the x-value of the vertex is x = 1.

FLASHCARD QUESTION
Front
What is the value of 'c' in the quadratic function f(x) = ax^2 + bx + c?
Back
The value 'c' is the constant term of the quadratic function. In f(x) = 3x^2 + 4x - 5, c = -5.

FLASHCARD QUESTION
Front
What is the standard form of a quadratic function?
Back
The standard form of a quadratic function is f(x) = ax^2 + bx + c, where a, b, and c are constants.

FLASHCARD QUESTION
Front
What does the coefficient 'a' indicate in a quadratic function?
Back
The coefficient 'a' indicates the direction of the parabola. If 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.

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