Thread: 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 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)
