Question

If you shift the linear parent function, f(x)=x, down 7 units what is the equation of the new function

Answer 1

f(x)=x-7 is indeed the correct answer.just got it right

Answer 2

To solve this problem you must apply the proccedure shown below:

1- You have that following parent function (the most basic function of the linear functions) given in the problem above:

f(x)=x

2- When you graph this parent function, you obtain the graph shown in the figure attached.

3- If you shift the linear parent function 7 units down, you have the following new function:

f(x)=x-7

4- The graph of the new function is shown in the second figure attached.

The answer is: f(x)=x-7
