Question

If ƒ(x)=−10x−6ƒ(x)=−10x−6, then ƒ^−1(x)=

Answer 1

To find the inverse:

Replace f(x) with y
Switch x's and y's, so put x where y is and x where y is.
Solve for y
Replace y with f^-1(x)

Answer 2

first rewrite the function as an equation
y=-10x-6
solve for x
y+6=-10x
-(y+6)/10=x
then write f^-1(y)
f^-1(y)=-(y+6)/10 or f^-1(x)=-(x+6)/10
then
check..
f(f^-1(x))=-10(f^-1(x))-6
can u finish from here...

Answer 3

sorry i just realized i typed it wrong

Answer 4

its if ƒ(x)=−10x−6, then ƒ^−1(x)=

Answer 5

i know ... thats the same function i did above...

Answer 6

okay so do i solve that?

Answer 7

All the steps are given, please try it out.

Answer 8

okay thank you
