SOLUTION: How to I find f(g(x)) and g(f(x)) ?
f(x) = x^2 - 5x + 2
g(x) = 2x
Would someone please show me how to solve these?
Thanks a million!

You can put this solution on YOUR website! How to I find f(g(x)) and g(f(x)) ?
f(x) = x^2 - 5x + 2
g(x) = 2x
---------------
f(g(x)) = f[2x] = (2x)^2 - 5(2x) + 2 = 4x^2 - 10x + 2
----------------------
g(f(x)) = g[x^2-5x+2] = 2(x^2-5x+2) = 2x^2 - 10x + 4
