Sagot :
bonjour
h (x) = - 2 x /3
h ( - 5 /2 ) = - 5 /2 x - 2/3 = 10/6 = 5 /3
- 2 x / 3 = 1
- 2 x = 3
x = - 3 /2
h ( 1 ) = - 3 /2
- 2 x / 3 = 3 /4
- 8 x = 9
x = - 9/8
Bonsoir,
h(x)= - 2x/3
Calculer
h(7)= - 2(7)/3= - 14/3
h(-5/2)= - 2(-5/2)/3= 10/6= 5/3
- 2x/3= 1 => -2x= 3 => x= -3/2
- 2x/3= 3/4 => 4(-2x)= 3*3 => x= -9/8
