Please help ASAP!

Answer 1

1. A

2. C

Explanation:

H in the parent function equations are always negative and k is always positive.

Ex:

`f(x)=2^(x-h)+k`

So that means when we're adding 4 to the exponent, we're actually subtracting, therefore moving the graph 4 units to the left.

Then, since k is positive, and we're adding 8, we move the graph 8 units up.
