Answer:
-5/4
Step-by-step explanation:
Answer:
Option A is correct answer.
Step-by-step explanation
If the given function is given as
f(x) =
then vertex is (h,k) and Its domain is set of all real numbers
and range is given to be y ≥k for a>0
So here in the question the equation is given as

on comparing the equation with given standard equation
we get a=3 which is greater than zero
h =1 and k=2
therefore vertex is (1,2) ,Domain is set of all real number
and range is y≥2
That is option A is correct!
