Question 433506
if I only know the vertex of a parabola is (-2,-5), is there a way to figure out an equation for the parabola? How?
No, an infinite number of parabolas can pass thru that vertex.
-----------------------
If I only know the zeros of a parabola are (-6,0) and (15,0) is there a way to figure out an equation for the parabola?  How?
The 2 zeros are -6 and 15.
---> (x+6)*(x-15) = 0
{{{x^2 - 9x - 135 = 0}}} is the equation.
