Question

Look at the graph and answer the following questions:



(3 points)
1) Is this graph increasing or decreasing?

2) Is this graph linear or nonlinear?

3) What is the domain?

Answer 1

I don't see the graph — can you upload the image or describe it (key points, end behavior, any open/closed dots)?

While I wait, here are quick ways to answer each question so you can apply them to the graph:

1) Increasing vs decreasing
- Increasing on an interval: as x increases, y increases (graph goes up left→right).
- Decreasing: as x increases, y decreases (graph goes down left→right).
- If it goes up for some x and down for others say where it increases/decreases or say “neither” if it changes direction.

2) Linear vs nonlinear
- Linear = straight line (constant slope). Also graph of y = mx + b.
- Nonlinear = any curved line or piecewise segments with different slopes.

3) Domain
- Domain = all x-values shown on the graph.
- Read leftmost and rightmost x-values covered. Use interval notation.
- If arrows at ends → extend to ±∞, write (−∞, ∞) or (−∞, a], [a, ∞), etc.
- Watch for open circles (exclude that x) vs closed dots (include that x).

If you upload the graph or describe its slope and endpoints/open circles, I’ll give the exact answers.
