Children’s cough syrup has dosage guidelines based on a child’s age. In the following piecewise function, x represents the child’s age in years and f(x) represents the dosage in fluid ounces.
f(x)=⎧⎩⎨⎪⎪0.5 if 1≤x≤31.0 if 3<x≤60.5x if x>6
Does the graph accurately represent the piecewise function? Why or why not?
(1 point)
Responses
Yes. The graph is correct because all three pieces of the function are present.
Yes. The graph is correct because all three pieces of the function are present.
Yes, because all of the points at the ends of the pieces of the function should have closed circles.
Yes, because all of the points at the ends of the pieces of the function should have closed circles.
No. The graph should be continuous, with all the pieces connected.
No. The graph should be continuous, with all the pieces connected.
No. There should be an open circle on the first point of two parts of the function.
