Answer:
An oblonger parabola translated left, rotated down and shifted up
Step-by-step explanation:
1) The parent function of
is
since it preserves its basic characteristics of a quadratic function and it is the simplest quadratic function, then it is a fair to say that.
2) Looking at the graph below
, this is a geometric transformation of 
When we do
, we oblong the parabola two times, translate it to left due to its addend +6 and rotate it down since there is a negative sign.
Finally, by adding +6 we shift it up.
Check the graph below, please.
