Answer:
f(x) is faster
Step-by-step explanation:
In case it is x^2 then f(x) will be faster.
If you draw these two function in the graph. You can see that
Or you can add any value randomly and see that
Ex:
when x = 5
f(x) = 25, g(x) = 10
when x = 20
f(x) = 400, g(x) = 40
when x is 4 times larger. g(x) is 4 times larger while f(x) is 16 times larger
