Someone please help.

Hi there!

There are 3 parts to this equation:

f(x)

f(x+1)

4f(x)

We must first determine these three parts separately.

1) f(x)

We're given that  :

⇒ :

2) f(x+1)

Now, we must find f(x+1). To do so, add 1 to x in the original function :

⇒

3) 4f(x)

To find 4f(x), multiply the original function by 4:

:

4) Put it all together

Now, plug each of the three parts into the equation :

Factor the left side

Divide both sides by 3^x

Because this equation is true, is therefore true.

I hope this helps!
