Answer:
3 units
Step-by-step explanation:
we know that
The y-intercept is the value of the function when the value of x is equal to zero
Looking at the graph
we have that
The y-intercept of g(x) is 2
Verify ---> For x=0 ---> g(0)=0+2=2
The y-intercept of f(x) is -1
Verify ---> For x=0 ---> f(0)=0-1=-1
Find the difference
[tex]2-(-1)=2+1=3\ units[/tex]
