Question

how do i find t^-1 (x) if t(x) = x^2 - 6x +5

Answer 1

First you make t(x) y then switch the variables x and y and isolate y then make y t(x) again

Answer 2

The problem with this function is that it is not one-to-one.

Answer 3

yeah i got (x-1) (x-5) = y.... i need to make x the subject of the formula... i don't know how to do that

Answer 4

let t(x)=y
so y=x^2-6x+5
solve for x
y-5+9=x^2-6x+9
y+4=(x-3)^2
sq.rt(y+4)=(x-3)
sq.rt(y+4)+3=x
now to find the inverse replace x with y ..and y with x
so sq.rt(x+4)+3=y

Answer 5

thank u
