Answer:
I believe the answer would be 21.
Step-by-step explanation:
the shadow of the tall flag is three times the small flag, so the height of the flag should also be three times the height. which is 21
<h3>A.</h3>
See below for a graph
<h3>B.</h3>
The inverse of a function appears on a graph as the reflection of the function across the line y=x. This is because the inverse relation is effectively the same relation with the variables x and y swapped. Here, the graphs of f(x) and g(x) are mirror images of each other across the line y=x, so we can see they are inverse functions.
The same technology allows us to graph y=f(g(x)) and y=g(f(x)). Both are graphs of y=x, as expected.
It’s -4 because it’s a negative slope first of all cause it’s going down, second you can see it goes down 4 then right 1 so the answer would be -4 :)
