Question

If f(x) = 2x − 4 and g(x) =one half x − 2, find f[g(−4)]

Answer 1

Given:-
\[f(x)=2x-4\]\[{g(x)}={{x \over 2}-{2}}\]. Now, we have to find the value of \[f[g(-4)]\]
so, first solve \[g(-4)={-4\over2}-{4}\],now put the value of g(-4)in the equation. then solve the f(-4/2-2).
and then u will get ur answer:)
