on considere la fonction g definie par g(x)=2x²-3x

 

calculer g(-2)

                g(0)

                g(1/2)

                 g (10³)

 

merci de detailler

Sagot :

G(1/2) = 2 x (1/2)2 - 3 x 1/2
= 2x 1/4 - 3/2
= 1/2 - 3/2
= -2/2
= -1

G(103) = 2 x 10^5 - 3x 10^3
= 200000 - 3000
= 197 x 10^3

G(-2)= 2 x (-2)2 - 3 x (-2)
= 2 x (-4) + 6
= -8 + 6
= -2

G(0) = 2x 02 - 3x 0
= 0 - 0
=0
