If we firstly consider only the terms in x.
subtract 2x from both sides of the equation
⇒5+2x
−2x=2x−2x
+6
Observe that the x terms are eliminated and we are left with
5+0=0+6 that is 5=6 which is invalid
There is no solution to this equation.
This is an exponential function.
Without any transformations (up or down), the range is y > 0
I would say the answer is B. Best of luck
