Okay, so we have f of x, we have f of x is equal to 3 to the x minus 7, and g of x is equal 3 to the x.
00:24
So as you can see, if you want to write f in terms of g, you can write f as f of x is 3 to x minus 7, but it's the same thing as if you plugged in x minus 7.
00:42
Into g so it's equal to g of x minus seven and i guess this is probably something in your textbook this means that you can make f from g by shift g to the right uh to the right by seven units so this so this tells you that the answer to the first one is a not d okay.
01:29
And now for the second problem, so this is the first answer, a.
01:33
The second one, you're correct.
01:35
The domain of the function is minus infinity to infinity.
01:38
So because there's no singularities.
01:41
So you can always take minus infinity to infinity.
01:43
So for the second one, the answer is minus infinity to infinity.
01:47
So you're correct there.
01:49
For a third one, though, let's look at 3 to the x minus 7.
01:56
And the range is what a value is...
