You can put this solution on YOUR website!
f(x) = 4x,,,, g(x) =x
,
make a T box
,
X,,,,,,,,,,f(x),,,,,,,,,,,,g(x)
0,,,,,,,,,,,0,,,,,,,,,,,,,,,0,,,,,,,,,,,,,,,both functions start at 0
1,,,,,,,,,,,4,,,,,,,,,,,,,,,1,,,,,,,,,,,,,,, f(x) is 4 times g(x)
2,,,,,,,,,,,8,,,,,,,,,,,,,,,2,,,,,,,,,,,,,,,,,,,,,,,DITTO
5,,,,,,,,,,,20,,,,,,,,,,,,,5,,,,,,,,,,,,,,,,,,,,,,,DITTO

as we can see for any given x, f(x) will be 4 times g(x), therefore it can be said to be growing 4 times faster
