Decide whether to construct a linear or exponential model from table values 4, 9, 14, 19 at equal intervals.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
test differences and ratios before writing function.
Hidden until you reveal it.
Data must contain enough evidence to distinguish constant difference from constant ratio.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Test for constant differences.
2. Test for constant ratios when appropriate.
3. Choose the model type supported by the consistent pattern.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Choosing from visual shape alone when table evidence is available.
