The answer is (-∞.∞).
Draw out a number line. Plot 0 and -4 on the number line.
Shade to the left of x = 0, and have a filled in circle at the endpoint. This is the graph of x≤0
Then graph x ≥−4 by plotting a filled in circle at -4, and shading to the right.
Note how the two graphs overlap to cover the entire real number line
So if we have x≤0 or x≥−4 then we're basically saying x is any real number. To write this in interval notation, we write (−∞,∞)
This is the interval from negative infinity to positive infinity (or just infinity). We exclude each endpoint because we can't actually reach infinity itself. Infinity is not a number. Infinity is a concept
Side note: if you change the "or" to "and", then the solution to x≤0 and x≥−4 would be [-4, 0][−4,0] to indicate the interval from x = -4 to x = 0, including both endpoints. This is the region where the two graphs overlap.

Equation of the first circle is (x - 1)² + (y + 2)² = 9 and that of the second circle is x² + (y + 2)² = 9
Step-by-step explanation:
- Step 1: Given the center of the first circle (h,k) = (1,-2) and radius, r = 3
Equation of the circle = (x-h)² + (y-k)² = r²
⇒ (x - 1)² + (y + 2)² = 9
- Step 2: Given the center of the first circle (h,k) = (0,-2) and radius, r = 3
⇒ x² + (y + 2)² = 9
