What function transforms the graph of the parent function f(x)=2^x by reflecting it across the y axis and translating it up 5 units?

Coefficient of x is less than 0 then it's across the y axis
So f(x)=2^x ---> g(x) = 2^-x
Then translating it up 5 units, should be g(x) = 2^(-x) + 5
Answer is the last one
g(x) = 2^(-x) + 5
Answer with explanation:
The given function is
[tex]f(x)=2^x[/tex]
Reflecting the function across y axis, gives
[tex]f(x)=2^{-x}[/tex]
Now translating the function by 5 units up, that is vertical translation,we get,
[tex]f(x)=2^{-x}+5[/tex]
Option D: [tex]g(x)=2^{-x}+5[/tex]
