Answer:
B
Step-by-step explanation:
Exponential functions are curves which approach a horizontal asymptote usually at y=0 or the x-axis. This function has been moved up 5 units so its asymptote is at y=5. This means the function never goes below 5 in its y-values.
The x values are not affected and all are in the function. This is the domain. So the domain is (-∞, ∞).
The y values are affected and are y > 5. This is the range and it is written
(5, ∞).
Option B is correct.
