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
same as, the intersection of the axis of symmetry and the parabola
Vertex
The point where the Axis of Symmetry and the Parabola intersect
same as, the point where the parabola reaches a maximum or minimum
Optimal Value
The y-value of the vertex
same as, the maximum or minimum value of the parabola
Optimal Value
The maximum or minimum value of a Parabola
same as, the y-value of the vertex
y-intercept
The point where a graph crosses the y-axis
all parabolas have 1 y-intercept
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
