bonjour
f (x) = 2 x² + 3 x - 1
il suffit de remplacer x
f ( 1) = 2 * 1² + 3*1 - 1 = 4
f ( 3) = 2 *3² + 3 *3 - 1 = 18 + 9 - 1 = 26
f ( -2 ) = 2 ( - 2)² + 3 *- 2 - 1 = 8 - 6 - 1 = 1
g (x) = 3 x + 2 + 1 / x
g ( 1) = 3 + 2 + 1/1 = 6
g ( 2) = 6 + 2 + 1/2 = 8.5
g ( 1/2 ) = 3/2 + 2 + 1 * 2 = 0.5 + 2 + 2 = 4.5
