Answer:

units.

Explanation:

The given functions are:

f(x)=3x-7

and

g(x)=3x+8

The function
f(x)=3x-7 has y-intercept ,
.

The function
g(x)=3x+8 has y-intercept,

If we shift the graph of g(x) up to obtain f(x), then the y-intercept must move from
to
.

This means that the graph will move up by;

8--7=8+7=15 units.
