Item 1 Question 1
The graph of which of the following functions does not belong with the other three?

$f\left(x\right)=3x^2+6x-24$

$f\left(x\right)=3x^2+24x-6$

$f\left(x\right)=3\left(x-2\right)\ left(x+4\right)$

$f\left(x\right)=3\left(x+1\right)^ 2-27$
Question 2
This is the only function that does not have x-intercepts at $x=$ Response area and $x=$ Response area and a vertex at (Response area , Response area).
