Question

I'm learning relations and functions. How would you solve f(x)=5/(x+2) if f(m-2)?

So far I plugged it in and have f(m-2)=5/([m-2]+2) but am confused on how to solve it

Answer 1

You are on the right track. Next combine like terms in the denominator. -2+2=0. This would leave you with just m in the denominator. So, f(m-2)=5/m
