Question

Which of the following transforms the graph of y=x^2 to the graph of y=x^2-7?

Answer 1

You're performing this kind of transformation:

$f(x)\mapsto f(x)+k$

This kind of transformations translate the functions vertically k units up if k is positive, k units down if k is negative.

So, in your case, you translate the function 7 units down.

Answer 2

Answer:

1.) a translation 7 units to the right

2.) a translation 7 units to the left

3.) translation 7 units down

4.) a translation 7 units up
