A, write an equation whose graph is a parabola whose vertex is (3/4,-3)
B, write an equation whose graph is a parabola that opens downward and has an axis of symmetry x=-4
C, Write an equation whose graph is a parabola opens upward and has a y-intercept of -1/2
D, Write an equation whose graph is a parabola whose vertex is (-3,4) with a y intercept of 1
A. the equation for a parabola with vertex...is
...so for
...is
B.the equation for a line facing down with its axis of symmetry at 4 is
C.one of the possibilities
D.to do this you need to set up your equation [tex]y=a(x+3)^2+4...I know...now all you have to do is say is put in your valuesand solve for a...so you get
...so your equation is
^2}{3}+4)
