Answer:
Firstly
f(x)=3x-2=y then
Interchanging x and y we get
x=3y-2
x+2=3y
y=(x+2)/3
f-1(x)=(x+2)/3
f-1(13)=(13+2)/3
f-1(13)=5
The denominator is the one on the bottom so 9 is the denominator the top is the numerator
Answer:difference of two squares will be
16y^2 -x^2 = (4y -x)(4y +x)
so the second choice
