Can anyone explain (solve) this:

Given f(x)=x(square) - 1 and g(x)=1 - 2x. Find the indicated values:

f(f2) and f(2f(1))

ASAP... Thanks! :)

Well we don't answer homework questions. But we can help you solve the problem. f(f(x))... that means you put the function f inside the function f. Use the existing functions and place them inside...


for example f=2x

f(f1/2(x)) would look like this 2(1/2(2x)
