Question

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

f(x) = 7x + 9
g(x) = 7x - 4

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

Answer 4

Let \(x=0\)

Answer 5

Then you have \(f(0)=9\) and \(g(0)=-4\)

Answer 6

So the two points here are \((0,9)\) and \((0,-4)\).
If you graph them, you will be able to see how far it moved.

Answer 7

Thank you :) @wio

Answer 8

@wio did it shift 13?
