Question

If g(x)= x+1/x-2 and h(x)=4-x, what is the value of (g o h)(-3)?

I keep getting 14/5... What am I doing wrong?

Answer choices are :
8/5
5/2
15/2
18/5

Answer 1

So from your question I assume you know that (goh) is using the function h ans the x value of the function g.

First step I would do is to put the function of H into G.

\[\frac{ (4-x)+1 }{(4-x)-2 }\]
Then just simplify it and Put in the value of -3=x

Oh.. I get it now. Thank you.!
