Front

What is the significance of the ordered pair (0, -2) to the graph?

Back

It is the y-intercept.

Front

Define Axis Of Symmetry.

Back

A line that divides the graph into two equal parts, cutting the graph in half.

Front

What are the green dots called on a graph?

Back

x-intercepts.

Front

What is the equation, in standard form, of a parabola that models the values in the table?

Back

y = 4x^2 + 6x - 2.

Front

Select the equation that results from the following transformations from y=x^2: Reflection across x-axis, Horizontal translation 2 units left, Vertical translation 5 units down.

Back

y=-\left(x+2\right)^2-5.

Front

What is a parabola?

Back

A symmetric curve formed by the intersection of a cone with a plane parallel to its side.

Front

What is the vertex of a parabola?

Back

The highest or lowest point on the graph of the parabola.

Front

What does the term 'rate of change' refer to in algebra?

Back

The ratio of the change in the dependent variable to the change in the independent variable.

Front

What is the standard form of a quadratic equation?

Back

y = ax^2 + bx + c, where a, b, and c are constants.

Front

What is the difference between x-intercepts and y-intercepts?

Back

x-intercepts are points where the graph crosses the x-axis (y=0), while y-intercepts are points where the graph crosses the y-axis (x=0).
