HEY MATE HERE IS YOUR ANSWER

BY FACTORISATION THE ZEROS ARE -3AND 4

THEN SUBTITUTE VALUES OF X =-2 -4 -1 0 1 2 3 4 5

$y = {x}^{2} - x - 12$
x=0
y=-12

x=-2
y=-6

x=-1
y=-10

x=2
y=-10

x=1
y=-12

plot them on the graph you will get an upward parabola as a>0

THEN WE WILL GET THE GRAPH

Answer 2

Answer

Put X =-2 -4 -1 0 1 2 3 4 5

y =  {x}^{2}  - x  - 12

x=0

y=-12

x=-2

y=-6

x=-1

∴y=-10

∴x=2

∴y=-10

∴x=1

∴y=-12
