Front

What is the formula to find the axis of symmetry of a quadratic graph?

Back

x = -b / (2a)

Front

What do we call the highest or lowest point of a quadratic graph?

Back

vertex

Front

What is the green dot on this quadratic graph called?

Back

Front

What is the standard form of a quadratic equation?

Back

y = ax^2 + bx + c

Front

What does the 'a' in the quadratic equation affect?

Back

The direction and width of the parabola.

Front

What is the vertex of the quadratic function f(x) = x^2 - 8x + 15?

Back

(4, -1)

Front

How do you find the y-intercept of a quadratic function?

Back

Set x = 0 and solve for y.

Front

What are the roots of a quadratic equation?

Back

The x-values where the graph intersects the x-axis.

Front

What is the significance of the discriminant in a quadratic equation?

Back

It determines the number and type of roots.

Front

What is the vertex form of a quadratic equation?

Back

y = a(x - h)^2 + k, where (h, k) is the vertex.
