27f(x)=1/4x^22x12. Can you show me how to find the vertex and x intercepts, stepbystep? I tried to put it in standard form, with (1/2x1)^213, but my book said that's not the answer. Thanks!

Is 27 the problem number or is that part of the equation?
If 27 is part of the equation, then
f(x) = (1/4)x^2 + 2x +39. That is not anything like your equation.
If the 27 is a problem number, you should not have types it as part of the equation. Is the minus sign in front of f(x) real, or a hyphen?
We can only answer math questions that are clearly written.

It's just the number of the problem.
