Graph the solution set of x ³ -9.
first of all give values for x like 0,1,-1,2,-2,3,-3,............
when x=0, we have y = 0^3 -9 = 0-9 =-9
when x= 1 we have y = 1^3 -9 = 1 -9 = -8
when x =-1 we have y = (-1)^3 -9 = -1 -9 = -10
when x = 2, we have y = 2^3 -9 = 8 - 9 = -1
when x = -2 we have y = (-2)^3 -9 = -8 -9 = -17
when x =3 we have y = 3^3 -9 = 27 -9 = 18
now we have the points like this,
(x,y)
(0,-9)
(1,-8)
(-1,-10)
(2,-1)
(-2,-17)
(3,18)
Now plot these points on the graph.
