Question

Dada a função f(x) 3x² - x + 2 determine f(x-1)

Answer 1

$Resolu\c{c}\~ao \to \left\{\begin{array}{ccc}f(x) = 3x^2-x+2\\\\f(x-1) =3(x-1)^2-(x-1)+2\\\\f(x-1) = 3(x^2-2x+1)-x+1+2\\\\f(x-1) = 3x^2-6x+3-x+1+2\\\\\boxed{\boxed{f(x-1) = 3x^2-7x+6}}\end{array}\right$

Espero ter ajudado. =^.^=
