Consider the quadratic functio(*zg4*jkegq on f(x(z l n3z1b+in)v ft:ah)=a$x^2$+bx+c. The graph of y=f(x) is shown in the diagram below. The vertex of the graph has coordinates R(m,−9).
The graph intersects the x-axis at two points; P(−4,0) and Q(2,0).
1.Find the value of m. m =   
2.Find the values of a, b, and c. a =    b =    c =   
3.Write down the equation of the axis of symmetry of the graph. x =
