Answer:

see below

Step-by-step explanation:

$f(x)=2/x\\\\g(x)=2/x\\\\f(g(x))=f(2/x)\\\\f(2/x)=2/(2/x)\\\\f(g(x))=2x/2\\\\f(g(x))=x\\\\$

and since f(x)=g(x) the same process applies to g(f(x))

See picture below. Being that you did not provide possible answers, I don't know what answer you can choose from.

There's probably a mistake in the problem; as written the answer is none of the above.

We have slope from the first two points of (4-2)/(0-4) = -1/2 and a y intercept from the second point of 4 so

f(x) = (-1/2) x + 4

maybe that's the third choice; forgot the fraction bar.

The formula for this is A= a + b/2 x h.
