These aren't that hard to identify......

We have the form

a (b)^{x}

When "b" > 0 but < 1.....we have decay

When "b" > 1 ...we have growth

[The "a" doesn't matter ]

So.....in the first part

h(x) = (0.2)^{x} and f(x) = 4(0.3)^{x} are decay functions

And...in the second part

h(x) = (1.9)^{x} and d(x) = 2(4.7)^{x} are growth functions
