1. What is the inverse of f(x) = x - 10?
with solution po sana.


Sagot :

Answer:

f(x) = x - 10

x = y - 10

x + 10 = y - 10 + 10

x + 10 = y

y = x + 10

Step-by-step explanation:

not sure tho.

Answer:

f^-1 (x) = x + 10

why? here are the steps

1.) replace f(x) to y

2.) Interchange x + y  

3.) Solve the new y from the equation in step 2

4.) replace the new y with f^-1 (x) if the inverse is a function

(step1)  y=x - 10  

(step2)  x=y- 10    [ -y = -x - 10 ]

(step3) y = x+10

(step4)  f^-1 (x) = x + 10
