    Only checking my answer

    The problem reads..Find the vertex, the line of symmetry and the maximum or minimum value of f(x)

    f(x)=1/2(x+2)^2 + 7

    vertex= (-2,7), line of symmetry is (-2), the maximum is 7

    am I right? if not just say no and I will try again.

    Very close...its not a maximum. Its a minimum, since the coefficient of \left(x+2\right)^2 is positive (which means the parabola opens upwards [like a smile])

    Everything thing else is correct. (the line of symmetry is the equation x=-2)
