2/9 is in simplest form as 2 and 9 do not have any common factors.
Answer:
By addition/subtraction
Step-by-step explanation:
If in domain:
f(x+a) or f(x-a)
If in range:
f(x)+a or f(x)-a
Where a is the number of units of translation
Answer:
C only
Step-by-step explanation:
C is the only one which is correct as in all the other options x is cancelled out as both sides have 2x which gets cancelled leaving the equation with something like:
31=31 which is true but it's not considered a "solution" and as A, B and D end up with stuff like this they are all not 1 solution. For c, as c doesn't have a power on top of it, like
does, its equation can only have 1 solution (or in some cases 0 solutions but this isn't one of them) so it is the correct answer.
B would make your answer true
