Answer 1

I don’t see the graph — could you upload it or describe it (shape, endpoints, any open/closed dots, arrows)? Then I’ll answer the three questions exactly.

Meanwhile, here’s how to decide each one so you can check quickly:

1) Increasing vs decreasing: look from left to right. If the y-values go up overall the graph is increasing; if they go down it’s decreasing. If it goes up in some places and down in others, it’s neither (or “increasing on intervals … and decreasing on intervals …”).

2) Linear vs nonlinear: if the graph is a straight line (constant slope) it’s linear. If it curves or changes slope, it’s nonlinear.

3) Domain: list all x-values shown on the graph. If the curve has arrows pointing left/right (continues forever), domain is all real numbers (−∞, ∞). If it only exists between x = a and x = b, domain is [a,b] (use parentheses if endpoints are open circles, brackets if closed dots).

If you upload the image I’ll give the exact answers.
