Coefficient A coefficient is the number in front of a variable.
Dilation To reduce or enlarge a figure according to a scale factor is a dilation.
domain The domain of a function is the set of x-values for which the function is defined.
Horizontal shift 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.
Parabola A parabola is the characteristic shape of a quadratic function graph, resembling a "U".
quadratic function A quadratic function is a function that can be written in the form f(x)=ax^2 + bx + c, where a, b, and c are real constants and a\ne 0.
standard form The standard form of a quadratic function is f(x)=ax^{2}+bx+c.
Symmetry A figure has symmetry if it can be transformed and still look the same.
Vertex 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.
vertical axis The vertical axis is also referred to as the y-axis of a coordinate graph. By convention, we graph the output variable on the y-axis.
