F(-4) = 3 x 2 - 5(-4) + 4
3x2= 6
-5(-4)= 20
6-20= -14
-14+4= -10
f(-4) = -10
4x-20+=-4
-4 -4
x-20=-8
+20 +20
x=12.
The answer is 20 you do multiplication first then the division, add what both the numbers that you got. Then subtract 37 and you get 20
If they get unexpected results they could note what they could've done wrong or what they could change in a next trail of experiments. Or look back and see what different happened to they could've hypothesized. There could be many different courses on what to do next.
Error! Because that does not make any sense
