Answer:

1 and 2 have already been done.

See below for the answers to 4 to 6.

Explanation:

7. Finding the limit as x --> 2 of the function:

(2^(x + 2) - 16) / (4^x -16)

= 4(2^x - 4) / (2^x -4)(2^x + 4)

= 4 / (2^x + 4)

When x = 2 this = 4/8 = 0.5

The limit is the same whether you approach 2 from below or above.

So k = 0.5.
