Answer:

f^{-1}(x)=25(x-2)^2

Step-by-step explanation:

The inverse function can be found by solving ...

  f(y) = x

  (√y)/5 +2 = x

  (√y)/5 = x -2 . . . . . subtract 2

  √y = 5(x -2) . . . . . . multiply by 5

  y = 25(x -2)² . . . . . square both sides

The inverse function is ...

  f^{-1}(x)=25(x-2)^2

<em>About the graph</em>

I need the answer and the work! <br> you have to find n.
zloy xaker [14]

Tell you what I'll do:  I'll show you the work, for two of them.
Then, knowing how to do it, you'll find the answers.
Deal ?

#1). n + (-13) = -12

Remove the parentheses
on the left side:                     n - 13 = -12

Add  13  to each side:           n        =    1

================================

#3).                        -15 + n  =  3

Add  15  to each side:     n  =  18


OK.  Look those over, understand how they're done, then TAKE IT !
