Write a polynomial function Parent function Transformations
Write a polynomial function. Parent function: Transformations: Polynomial Function:
Solution
given log1/3(x2+x) -log1/3(x2-x) =-2
logA-logB=log(A/B)
log1/3 [(x2+x)/(x2-x)] =-2
[(x2+x)/(x2-x)] =(1/3)-2
[x(x+1)/x(x-1)] =32
[(x+1)/(x-1)] =9
(x+1)=9(x-1)
(x+1)=(9x-9)
9x-x-9-1=0
8x-10=0
2(4x -5)=0
x=5/4
solution set is 5/4
