Question

Choose the function that represents the data in the table.



y =
y = 2x – 3
y = 2x – 3
y = 2x2 – 3

Answer 1

I don't see the table — could you paste the x and y values (or an image)?

How to choose once you give the table:
- Plug any point (x,y) into each candidate function. If a function fails for any point it's not the correct model.
- Quick checks:
- If the y-change for equal x-steps is constant (first differences constant) the relationship is linear (y = 2x − 3 would require slope 2 and intercept −3).
- If the first differences are not constant but the second differences are constant, it's quadratic (y = 2x^2 − 3 would give second differences equal to 4).

If you paste the table I will test the options and tell you which one matches.
