The equation of the quadratic funtion represented by the graph is y=a(x-3)^2 -1. what is the value of a?

(x-3)^2|| using (a-b)^2=a^2-2ab+b2|x^2-2x*3+3^2calculate: -2x*3^2 = -6xx^2-6x+3^2evaluate the power: 3^2 = 9x^2-6x=9y=a*(x^2-6x+9)-1distribute "a" through the parenthesisy=ax^2-6ax+9a-1therefore, y=ax^2-6ax+9a-1now that we have "y", it'll be simple to figure out "a". good luck!
