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
