Let f(x)=10x-10 find the value of (fof^-1)(-10)

(f o  f^-1  (10))  =  10

Step-by-step explanation:

f ^ -1  =  (x + 10)/10

from solving  from  f(x) = 10x - 10

since  10x - 10  is a  one-to-one function  it has an inverse

so  f o  f^-1  (x)  =  x

(f o  f^-1  (10))  =  10

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
