Q: Not all functions have inverse functions. In order for a function f: X Y to have an inverse, it must have the property that for every y in Y there must be one, and only one x in X so that f(x) = y. This property ensures that a function g: Y X will exist having the necessary relationship with f.
Can we conclude that if a function is not one to one does it have an inverse?
OPTIONS:
- no
- yes
A: no

Q: A direct-injected twin-turbocharged EcoBoost engine is available for the 2010 model. The EcoBoost produces 355 hp (265 kW) and 350 lbft (470 Nm) of torque. In 2013, the Flex gained 10 horsepower to make a total of 365 hp (272 kW), while the torque remained the same.
