I'm super confused on parts g and h because no formula is given, just the limit values. These are the values: lim f(x) = 16
x is approaching 4

lim g(x) = -2
x is approaching 4

See below.

Step-by-step explanation:

1)

So we have the limit:

This is equivalent to:

To solve, we can use the following property:

Therefore, our limit is the same as:

We are already given that the limit as x approaches 4 of g(x) is -2. Therefore:

You simply need to evaluate this to solve the limit. I don't have enough information to solve this, so maybe you have something more.

Similarly, for the second one:

2)

We have:

Using the same property:

And we are told that this is 16, so:

And we just need to evaluate this to find the limit.

I hope you find this helpful!
