Answer 1

I don't see the graphs. Could you either upload the image(s) or briefly describe each graph (for each of a, b, c: is it a line, parabola, circle, set of points, vertical line, horizontal line, etc., and any key points)?

If you want to answer them yourself right away, use these quick tests and sample answer wording:

- A (Which graph(s) are not a function?)
- Test: apply the vertical line test. If a vertical line intersects a graph in more than one point, that graph is NOT a function.
- Sample answer wording: "Graph ___ is not a function."

- B (Why are the graph(s) NOT a function?)
- Explain: "Because a vertical line at x = ___ intersects the graph in more than one point, so a single x-value gives multiple y-values."

- C (Which graph(s) are NOT linear?)
- Test: a linear graph is a straight line. Anything curved (parabola, circle, exponential curve, piecewise non-straight, etc.) is not linear.
- Sample answer wording: "Graph ___ is not linear because it is [describe shape], not a straight line."

- D (Which graph(s) have a constant rate of change?)
- Test: constant rate of change ⇔ graph is a straight line (linear). So list the linear graphs.
- Sample answer wording: "Graph(s) ___ have a constant rate of change because they are straight lines."

If you upload or describe the three graphs, I will fill in A–D exactly.
