Answer:
Option C [tex]f(x)=\sqrt{x-1} +4[/tex]
Step-by-step explanation:
we know that
Observing the graph
The domain of the function is the interval ------> [1,∞)
[tex]x \geq 1[/tex]
All real numbers greater than or equal to 1
The range of the function is the interval -----> [4,∞)
[tex]y \geq 4[/tex]
All real numbers greater than or equal to 4
therefore
The function is equal to
[tex]f(x)=\sqrt{x-1} +4[/tex]
