1.1 Parabola Language Flashcards
To learn the common language used to describe the graph of a Parabola
Parabolas can Open
Up or Down
x-intercepts
Where a graph crosses the x-axis
x-intercepts, roots and zeros are all the same thing
Roots
Where a graph crosses the x-axis
x-intercepts, roots and zeros are all the same thing
Zeros
Where a graph crosses the x-axis
x-intercepts, roots and zeros are all the same thing
Axis of Symmetry
Vertical line that divides a parabola into 2 equal halves
Vertex
The point where a parabola reaches a maximum or minimum
Vertex
The point where the Axis of Symmetry and the Parabola intersect
Optimal Value
The y-value of the vertex
Optimal Value
The maximum or minimum value of a Parabola
y-intercept
The point where a graph crosses the y-axis
Leading Coefficient
The constant multiplier for
the highest power term
y=ax² or y=5x²
a is the leading coefficient & x² the highest power term for parabolas
