Answer:
f(x) = (√x) + 3
Step-by-step explanation:
This function is a translation of the parent function, f(x) = √x. A translation slides a graph. In this case, we can see that the function has been slid, or shifted, 3 units up. This is represented in a function by adding 3 to the end of the function; thus it is f(x) = (√x) + 3.
A.
