does anyone know a good way to remember the difference between the domain and range?? if so can you tell me??

Yay
remember that you can do anything to an equation as long as you do it to both sides
also
log(a)-log(b)=log(a/b)
and
if no base is stated, then probably base 10
also,
translates to 
so
log(t-3)=log(17-4t)
minus log(17-4t) from both sides
log(t-3)-log(17-4t)=0
translate
remember, base 10
times both sides by 17-4t
17-4t=t-3
add 4t both sides
17=5t-3
add 3 both sides
20=5t
divide both sides by 5
4=t
t=4
