Question

How do I find the zero of this function? (click to see equation, I'm working on it)

Answer 1

\[F^-1(x)\] if \[F(x) = x + 3\]

Answer 2

If \[ F(x)=x+3 \] then \[ F^{-1}(x) = x-3 \]
Can you find the zero of that?

Answer 3

It is zero when x = 3

Answer 4

\[f(0)=0+3=3....................f ^{-1}=0-3=-3\]

Answer 5

\[F(0)=3\]

so \[F^{-1}(3)=0\]

Answer 6

I think I get it, but what does the -1 on the F mean? what am I supposed to do to the equation? I thought a negative exponent turned it into a fraction...?

Answer 7

inverse function

Answer 8

YTheManifold gave you the inverse function if you want it

Answer 9

Ohh, now I get it. Thank you guys! :)
