Answer:

Explanation:
Horizontal translation:
if y =f(x) , then y = f(x+h) is horizontal translation.
The translation h moves the graph to the left when h is the positive value and to the right when h is negative.
As per the statement:
Given the graph:

It has been translated 7 units to the left
By definition:
h = 7 units > 0
then, the equation becomes;

Therefore, the equation of the resulting parabola is,
