  3. Graph A= (-67.4,0) B=(75,0) C=(-45,120) D=(-35.5,109) E=(0,180)

  4. E= 180=a(0)^2+b(0)+c= 180=c A=a(-67.4)^2-67.4+c 4542.8a-67.4b+c 0=a(75)^2+75b+c 0= 5625a+75b+c Math

  5. -180=4542.8a-67.4b)75 -180=5625a+75b)67.4 -13500=340710a-5055b -12132=379125a+5055b -25632=719835a -0.0356=a Substitution: c=180

  6. -180= 5625(-0.0356)+75b -180=-2002959+75b 20.2959=75b .2706=b F(x)=-.0356x^2=.2706x+180 Substitution: a=-0.0356

  7. F(x)=a(x-h)^2+k F(x)=-.0356(x-h)+k F(x)=-.0356x^2+.2706x+180 F(x)=-.0356(x^2+.2706x+14.44)+180+.514 F(x)+-.0356(x-3.8)^2+ 180.514 Vertex Form

  9. If a rocket ship launches from point A, what will be its highest point, point E, and where will it land B. If Calli throws the dog toy and it bounces once, point A, goes up, Point E, and then lands point B. Real life Situation
