4x + 6 < -6
subtract 6 from both sides
4x < -12
divide 4 on both sides
x < -3
I'm not sure how long you want this, but I did it when x = 0 all the way to when x = 5.
x y
0 5
1 4
2 3
3 2
4 1
5 0
For the given quadratic equation we only have a maximum at y = 18.
<h3>
How to find the extrema of the given function?</h3>
Here we have:

Notice that this is a quadratic equation of negative leading coefficient.
Then we have a maximum at the vertex, and both arms tend to negative infinity as x tends to infinity or negative infinity.
The vertex is at:
x = -(-4)/(2*(-2)) = -1
The maximum is:
