Question

The graph of y = x 2 has been translated 7 units to the left. The equation of the resulting parabola is _____.

y = (x - 7) ²

y = (x + 7) ²

y = x ² - 7

y = x ² + 7

Answer 1

to move the function to the left you have to increase x inside the function
think of it like g(x)=f(x+7)

the solution is
y=(x+7)^2

Answer 2

Answer:

I had the same question, and got it right.

So, the answer would be $y = ( x + 7)^2$. :)

So, your answer is the second choice. :)

Hope you have a great day! :)

May God bless youuuuu <3 :)
