bonjour
ex 3)
h ( x ) = ( 2 + x ) * 3
on calcule h (-10)
h (-10) = ( 2 - 10) * 3
h(-10) = - 8 * 3
h(-10) = - 24
on calcule h (1)
h (1) = ( 2+ 1 ) * 3
h (1) = 3*3
h(1) = 9
on calcule h ( 10 )
h ( 10 ) = ( 2+10 ) * 3
à toi de terminer
ex 4 )
p(x) = x³ - x ²
on calcule pour p(-2)
p(-2) = (-2)³ - ( -2)²
p(-2) = -8 - 4
p(-2) = - 12
on calcule pour p(-1)
p(-1) = (-1)³ - (-1)²
p(-1) = -1 - 1
p(-1) = - 2
on calcule p(1)
p(1) = 1³ - 1²
p(1) = 1-1
p(1) = 0
à toi de faire la dernière ; )
bonne continuation ☺️
