the vertex is given in the graph as (-3,2)
the formula for vertex is y=a(x-h)^2+k
so looking at the this there and the given choices the 3rd anwer is correct
the first number (-3) is the opposite of the number I n the first set of ()
the 2nd number (2) is the same number at the end of the equation
so y=(x+3)^2+2
