The first inequality is already in terms of x:
x ≤ 0
x is everything to the left of zero (including zero) so you use a closed circle for 0:
<==========@ ------------------>
-3 ... -2 ... -1 .... 0 ..... 1..... 2 ..... 3
The second inequality needs to be solved for x:
x + 6 > 3
Subtract 6 from both sides:
x > 3 - 6
x > -3
In this case x is everything to the right of -3 (but not -3) so you use an open circle.
<----- O======================>
-4 ... -3 ... -2 ... -1 .... 0 ..... 1..... 2 ..... 3
The place where both of these overlap is between -3 and 0
<----- O==========@ ------------------>
-4 ... -3 ... -2 ... -1 .... 0 ..... 1..... 2 ..... 3
-3 < x ≤ 0
In interval notation:
(-3, 0]

f(x) = (x+2)(x-a million)(x-3)<=0 Make a table, concentrating on the periods x>3 a million

x<=0
the solution set for this would be (-infinity, 0]. (sorry can't graph it)
x + 6 > 3
x > -3
the solution set for this is (-3, infinity).

X is -3 or greater

No offense, but shouldn't you be asking your teachers that? That what they are there for. Don't be shy.
