Okay, here we have this:
Considering the provided function, we are going to calculate the requested values to complete the function table, so we obtain the following:
x=-2:
f(x)=-3x+2
f(-2)=-3(-2)+2
f(-2)=6+2
f(-2)=8
x=-1:
f(x)=-3x+2
f(-1)=-3(-1)+2
f(-1)=3+2
f(-1)=5
x=0:
f(x)=-3x+2
f(0)=-3(0)+2
f(0)=0+2
f(0)=2
x=1:
f(x)=-3x+2
f(1)=-3(1)+2
f(1)=-3+2
f(1)=-1
x=4:
f(x)=-3x+2
f(4)=-3(4)+2
f(4)=-12+2
f(4)=-10
