Answer 1

The y = 2 should give it away, how many units up is it?

Answer 2

It's just like any other function, so we have our parent function \[f(x) = (1/2)^x\] how many units is it translated upwards, that will give you \[f(x) = (1/2)^x +k\] your k value

Answer 3

right. the answer is option d.

though, could you perhaps answer this last question of mine?

Answer 4

Yes, D is right, alright lets see.

Answer 5

Ok so the same thing applies here, the log base 2 function is as such this is our parent function so we need to apply horizontal scaling here and again vertical translation
