Answer:

For a function f(x), a vertical stretch of scale factor K is written as:

g(x) = k*f(x)

And for a function f(x), a vertical translation of N units is written as:

g(x) = f(x) + N

If N is positive, the translation is up

if N is negative, the translation is down.

1) We have the function:

y = f(x) = 5^(x - 2)

A vertical stretch of factor 3 will be:

y = g(x) = 3*f(x) = 3*(5)^(x - 2)

2) We have the function:

y = f(x) = 7.2^x

A translation up of 8 units will be written as:

y = g(x) = f(x) + 8 = 7.2^x + 8
