Question

The f(x)= -3x + 4
the range is
(-2, 0, 4, 8)
Find the domain

Answer 1

range is output

domain is input or x

basically


-2=-3x+4
0=-3x+4
4=-3x+4
8=-3x+4

solve for x

minus 4 from alll of them
-6=-3x
-4=-3x
0=-3x
4=-3x

divide both sides by -3
2=x
4/3=x
0=x
-4/3=x

domain={-4/3, 0, 4/3, 2}
