Answer:
f(x) = 3 if x ≤ -2
= 1 if x > -2 ⇒ attached figure
Step-by-step explanation:
* Lets explain how to answer the question
- For the part of the graph on the left side (2nd quadrant)
- There is a horizontal line start from x = -∞ and stop at x = -2
- The end of the line is black dot means x = -2 belongs to the function
- The horizontal line drawn at y = 3
∴ The equation of the horizontal line is y = 3
∴ The function represents this part of graph is y = 3 if x ≤ -2
- The other part of the graph is also horizontal line start from
x = -2 to x = ∞
- The end of the line is white dot means x = -2 does not belong
to the function
- The horizontal line drawn at y = 1
∴ The equation of the horizontal line is y = 1
∴ The function represents this part of graph is y = 1 if x > -2
* f(x) = 3 if x ≤ -2
= 1 if x > -2
- The answer is attached

The geometric mean is different than algebraic mean - algebraic is adding up all the numbers and dividing it by the number of numbers, but geometric is multiplying them and getting the root of the product of all the numbers. For example, if there were 10 numbers, we would have the 10th root of the product of all the numbers or the product to the power of 1/10.
Since there are 2 numbers, we simply have the square root -
due to that 2²=4, so we can divide what is in the square root by that and take the 2 out.
