Answer:
The vertex of the parabola is (-2,0)
Step-by-step explanation:
The given function is:
Now, in order to find the vertex for the parabola, that is v(h,k), comparing the above equation with the standard form of equation that is 
, we get
a=-3, b=-6 and c=0
We know, 
and 
, therefore
and 
Thus, the vertex is given as:(h,k)=(-2,0).

Answer:
x < -7
Step-by-step explanation:
An inequality is solved similar to an equation with the exception that when multiplying or dividing by a negative coefficient, the sign must flip in the other direction. The original inequality is:
-6x > 42
To solve, you need to divide both sides of the inequality by -6, however, since you are dividing by a negative coefficient, the sign need to flip the other way:
-6x/-6 > 42/-6 = x < -7
