Is knowing the coordinates of the vertex of a parabola enough to determine the domain and range?
a. no: we would have no information about the domain.
b. yes: if the vertex is at (m, n), then the domain is all reals and the range is y ≤ n.
c. no: we would need to know if the vertex is a minimum or a maximum.
d. yes: if the vertex is at (m, n), then the domain is all reals and the range is y ≥ n.
use a graphing calculator to approximate the vertex of the graph of the parabola defined by the following equation.
y=2x-x+6
a)( 0.25, 6.125)
.25, 5.875)
c)( 0.25, 5.875)
d)( 0.25, 6)
