+18 A parabola opening up or down has vertex (0,2) and passes through (4,6)
Write its equation in vertex form.
+36915 vertex will be the high (mound shaped) or low point (bowl shaped)
the point given is HIGHER than the vertex .... so this is bowl shaped
+36915 Vertex (h,k) = (0,2)
vertex form y = a(x-h)^2 + k
y = a (x-0)^2 + 2
\sub in the point given to calc 'a'
6 = a4^2 + 2
4 = 16a a = 1/4
y = 1/4x2 + 2
+18 can i give u more questions to answer, just do it as fast as u can, u dont have to show the work
A parabola opening up or down has vertex (0,-3) an passes through (10,-8). Write its equation in vertex form
+36915 Just do it the same way I just did your first question......if you understand THAT answer , you can do this one with diferent numbers ......
