To determine whether a graph accurately represents a piecewise function for children's cough syrup dosage, I would need to see the specific piecewise function you're referencing, including the age ranges and their corresponding dosages. However, without that specific information, you can consider the following characteristics to evaluate if the graph aligns with the piecewise function:
-
Correct Age Ranges: Each segment of the graph should correspond to the defined age ranges in the function. For example, if the function specifies different dosages for ages 1-2, 3-5, and 6-12, the graph should have distinct segments that reflect those age ranges.
-
Continuous vs. Discontinuous: A piecewise function may have discontinuities at the boundaries of the segments (e.g., a change in dosage at age 2 or age 5). The graph should reflect these jumps, meaning the graph should not connect at those points unless specified otherwise in the function (e.g., if it's a closed interval).
-
Dosage Values: The y-values (dosage) at each corresponding age x should match what is stated in the piecewise function. If the function states that ages 1-2 get 1 ounce, the graph should reflect a height of 1 at x = 1 and x = 2 (if inclusive).
-
Endpoints and Open/Closed Circles: If the function specifies open or closed intervals, ensure that the graph uses open circles for open intervals and filled circles for closed intervals at the relevant points.
If you provide the specific piecewise function, I can give a more precise assessment.
