Answer:
80 is the measure because if aob is 40 then doe is 40 and dof is 120 minus the doe that 40 then you are going to get the mesuare which is 80
The correct answer is letter A. It’s an exponential parent function. They are always curved like that.
I'd say option D because you can just tell right off the bat that if x = 0, then f(x) = 43.75.
