Answer 1

Not your fault, of course, but k is missing from the parent function. Where would you put k? Could you possibly ask your teacher for clarification?

Answer 2

Hints:
Standard transformations of function f(x) into g(x):
\(g(x)=a f(bx-h)+k\)
where
a=vertical stretch (when a>1)
1/b=horizontal stretch (when 1/b >1)
h=translation to the right (when h>0)
k=translation up (when k>0)

Answer 3

k > 0 moves the graph up, k < 0 moves the graph down.
