Answer:
See explanation
Step-by-step explanation:
Given the inequality 
A) Add -3 to both sides of inequality:

Divide by -7 (remember, dividing the inequality by negative number changes the sign of inequality):

B) Plot open circle at -6 on the number line and shade all values of x which go to the left from -6 (see attached diagram).
The given function is greater than or equal to 0 for the interval given as follows:
{x | x ≤ -3 or -1 ≤ x ≤ 0 or x ≥ 2}.
<h3>When a function is positive and when it is negative?</h3>
- A function is positive when it is above the x-axis.
- A function is negative when it is below the x-axis.
For this problem, with a closed interval, we have that the function is above for:
x ≤ -3, -1 ≤ x ≤ 0, x ≥ 2.
Hence the interval notation is:
{x | x ≤ -3 or -1 ≤ x ≤ 0 or x ≥ 2}.
