Question

The functions f(x) and g(x) are described below:

f(x) = 3x − 7
g(x) = 3x + 8

The graph of g(x) is obtained by shifting up the graph of f(x) by _____ units.

Answer 1

do u need these two points to be grafted? If so there is a website called desmos.com that you can go to and it will plot them for you.
If you need them to be solved i need numbers, to solve them for u. i hoped that helped

Answer 2

one way is this
y=mx+b
b=y intercept


f(x)=3x+7
g(x)=3x-8


f(x) has y intercept at y=7
g(x) has y intercept at y=-8
distance between them is 15 units down


another way
to move a graph c units up, add c to whole function
f(x)=3x+7
to g(x)=3x-8
added -15 to the funtion
moved it up -15 units or down 15 units
