Question

Fungsi f : x dipetakan( tanda panahc) 3x - 5 dgn x = {-3,-2,-1,0,1,2}.
tentukan daerah hasil fungsi f !



secepatnya yaa

Answer 1

Daerah hasil= -14, -11, -8, -5, -2, 1

Answer 2

 f(x) = 3x - 5
x= {-3,-2,-1,0,1,2}

x= {-3} 
f(-3) = 3(-3) - 5
= -9-5 = - 14

x= {-2}
f(-2)= 3(-2) - 5
= -6 - 5
= -11

x={-1}
f(-1)= 3(-1) - 5
= -3 - 5
= -8

x={0}
f(0) = 3(0) - 5
= 0-5
= -5

x={1}
f(1) = 3(1) - 5
= 3-5
= -2

x={2}
f(2) = 3(2) - 5
= 6 - 5
= 1
