Bonsoir,

on considère la fonction h(x) = -2,4x

a. Complète

h(5) = -2,4 * 5 = -12

h(-5) = -2,4 * (-5) = 12

b.

h(7) = -2,4 * 7 = -16,8

c.

h(-3) = -2,4 * (-3) = 7,2

d.

h(x) = 24

-2,4x = 24

-2,4x / (-2,4) = 24 / (-2,4)

x = -10

h(-10) = 24

e.

h(x) = -0,6

-2,4x = -0,6

-2,4x / (-2,4) = -0,6 / (-2,4)

x = 0,25

h(0,25) = -0,6

* = multiplication

/ = division

Bonne soirée
