Question

If F(x) = 2x - 1, find the zero of F -1(x).


-1
1/2
1

Answer 1

replace \(x\) by 0 and see what you get

Answer 2

let f(x)=y
y=2x-1
this gives, x = (y+1)/2
If f(x)=y, then f^-1(y) = x
So, f^-1(y) = (y+1)/2
=> f^-1(x) = (x+1)/2

Answer 3

I think he asked about the inverse function? @satellite73

Answer 4

Its SHE @AbhimanyuPudi lol and is the answer gonna be -1/2x - 1

Answer 5

Ohhhhh sorrrrrry...@minnie123

Answer 6

Are you asking f(-1) or f^-1(x)

Answer 7

find the zero of F ^-1(x).

Answer 8

Okay
f^-1(x) = (x+1)/2
So, 0 = (x+1)/2
0 = x+1
Then x = ?

Answer 9

1?

Answer 10

No....
0 = x+1
Subtract 1 on both sides
0-1 = x+1-1
-1 = x

Answer 11

oh yeah don't know what i was thinking... :/ thanks

Answer 12

welcome:)
