Answer:
The easiest way to do without diffferentiating is analyzing the funtion in detail.
a) is a cubic function and has a positive leading cofficient. So it would be E graph.
b) is a quadratic function so it is A graph which is the only quadratic function among figures.
c) is C graph you can know easily if you draw it.
d) is a cubic function and has a negative leading cofficient. So it would be D graph.
Additionally, grach C is an exponential function.
