URGENT PLEASE ANSWER <br> inverse function<br> *see attachment*
Mila [183]

Answer:

Horizontal shift to the RIGHT of <u>one unit</u>

Step-by-step explanation:

When looking at a square root equation, the transformation form is:

f(x) = a\sqrt{b(x-h)} +k

'h' represents a horizontal shift of the graph. Therefore, in this instance:

f(x) = \sqrt{x-1}

This means that there is a horizontal shift to the RIGHT of <u>one unit.</u>
