Question 302669
g(x) is a straight line with a slope of 1.
f(x) is exponential.  Its slope is less than one for x<0 and greater than one for x>0.
-------------
There would be one value of x where the slope is 3, and where it is 4.
For all other points, the answer is no.

PS  3 times faster = 4 times as fast.
