I thought it might be x-2,-7 but that is not an option

mmhmm, that's weird. If the function is $\ f(x) = 3x^2 + 12x + 5$

Then the vertex is indeed (-2, -7)

hhanan · Answer

The only options are 
(-2, 41)
(2, 41)
(-2, 7)
(2, 7)

Are you sure that the equation isn't

$ f(x) = 3x^2 \color{red}{ -}12x + 5$

You'll just have to choose a random answer and then reach out to your teacher because there is a typo in the question.

Yes see the typo may mislead us to get or end up with a very different answer and that may cause you to end up being wrong. thus (wrong answer = wrong question answer)
