Question

plz hlp me to solve this equation

y-x²-6x+9=0

XD

Answer 1

sorry but that doesn't help :(

Answer 2

y-x²-6x+9=0
y=x²+6x-9=0 or
x²+6x-9=0 can you go from here to solve the quadratic eq?

Answer 3

no i'm supposed to find the expression of the inverse function of this
f(x)=(x-3)²-1
i did this
f(x)=y <=> f^-1(y)=x
<=> y=(x-3)²-1
now i must find the expression by x
plz help me

Answer 4

so this is not the problem anymore?

Answer 5

y-x²-6x+9=0

Answer 6

f(x)=(x-3)²-1 then
y=(x-3)²-1
y+1=(x-3)²
(y+1)^1/2=(x-3)
(y+1)^1/2 +3= x
now the inverse is
f^-1(y)=(y+1)^1/2 +3 ans

Answer 7

thanx you very much :)
