1) f(x)=-3x + 2
2)f(-5)= -3(-5) + 2= 15 +2=17

f(-2)= -3(-2) +2= 6+2=8

f(0)=-3(0) + 2= +2

f(3,5)= -3(3,5) + 2= -10,5 + 2= 8,5

f(7)= -3(7) + 2= -21 + 2= -19

3) f(-4)= -3(-4) +2= 12 + 2= 14

f(-1)= -3(-1) + 2= 6

f(2)= -3(2) +2= -6 +2= -4

f(5)= -3(5) +2= -15 + 2= -13

f(13)= -3(13) +2= -39 +2= -37
