If f(x) = 4x^2 + 3x - 2 write down the following in their simplest form.

a) f(x) +4 = 4x^2 + 3x - 2 +4

= 4x^2 +3x + 2 (this one I think i understand.)

b) f(2x) + 2 = i dont know how to do this one.

= 2( 4x^2 + 3x - 2) +2?

c) f(x+2) - 20 = ?

d) f (x-1)+1 + ?

e) f(x/2) = 4x^2 + 3x - 2/2 ??

f) f (3x+2) =?

If you explained b) i'd be able to figured out f) i hope, and if you explained just one from c) or d)

Thank you so much.
