A coefficient is the number in front of a variable.
To reduce or enlarge a figure according to a scale factor is a dilation.
The domain of a function is the set of -values for which the function is defined.
A horizontal shift is the result of adding a constant term to the function inside the parentheses. A positive term results in a shift to the left and a negative term in a shift to the right.
A parabola is the characteristic shape of a quadratic function graph, resembling a "U".
A quadratic function is a function that can be written in the form , where , , and are real constants and .
The standard form of a quadratic function is .
A figure has symmetry if it can be transformed and still look the same.
The vertex of a parabola is the highest or lowest point on the graph of a parabola. The vertex is the maximum point of a parabola that opens downward and the minimum point of a parabola that opens upward.
The vertical axis is also referred to as the -axis of a coordinate graph. By convention, we graph the output variable on the -axis.
Graph and compare graphs of quadratic functions in the coordinate plane.
