Lascia che f (x) = 9x – 2 e g (x) = -x + 3, come trovi f (g (x))?
Lascia che f (x) = 9x – 2 e g (x) = -x + 3, come trovi f (g (x))? Risposta: f(g(x))=-9x+25 Spiegazione: Substitute x = – x + 3, that is g(x) into f(x) f(g(x))=f(color(red)(-x+3)) color(white)(f(g(x)))=9(color(red)(-x+3))-2 color(white)(f(g(x)))=-9x+27-2 color(white)(f(g(x)))=-9x+25
