Given: y=0.2(3.8)x
For a. function, y=abx,
- the function represents exponential growth if a>0 and b>1.
- the function represents exponential decay if a>0 and 0<b<1.
In either case, the y-intercept is (0,a).
From the given, a=0.2 and b=3.8. Because 2>0 and b>1, then the function represents an exponential growth and the y-intercept is (0,0.2)
