functions

[crystal vault]

IK how to go abt it but every time I get x/a^2-a+1 instead of x like I’m supposed to

,rotate

[trail perch]

sorry looks bad but it follows from there

[crystal vault]

Ye so that’s how u get f^-1 but don’t I need to find f^2 to prove it’s self inverse?

[trail perch]

why

doesnt f(x) = f^-1(x) mean self inverse

[crystal vault]

Self inverse means f^2=x

Ohhhh

I see

[trail perch]

oh u mean ff by f^2?

[crystal vault]

Ye

[trail perch]

yeah so f(x) = f^-1(x) then f both sides so
ff(x) = x

[crystal vault]

Ok

[trail perch]

so proving f = f^-1 is enough

K thanks

bro damnn

u in y10 learning this shi damnn

[crystal vault]

These questions are almost always in Hamilton papers asw

[alpine jolt]
