Jika fungsi h(x)= 5x-c,dan nilai h(4)=13,maka nilai h(-5) adalah......

h(x)= 5x-c←→ h(4)=13
h (4) : 5 (4)-c=13
20-c=13
c=7

h(x)= 5x-7
h (-5) = 5 (-5)-7
h (-5) = -25-7
h (-5) = 32

h(x)= 5x-c, jika h(4)=13 maka:
h (4) = 5 (4)-c=13
20-c=13
-c=13-20
-C=-7
C=7

h(x)= 5x-c
h (-5) = 5 (-5)-7
h (-5) = -25-7
h (-5) = -32
