A parabola graph has the Vertex and Y-intercept is A(0,8) and x-intercepts of B(3,0) and C(-3,0)....
Question 1) The parabola has the equation ax^2+bx+c , Use "A(0.8)" to find the value of "b" and "c" from the equation ax^2+bx+c
Question 2) Use B(3,0) to find value of "a" which belongs to ax^2+bx+c
