A gas station is offering a deal. If you buy 10 gallons or more of gas, you will be charged $2.25 per gallon instead of the regular $2.50 per gallon. The deal is modeled by the following piecewise function. f(x)={2.5x if x<102.25x if x≥10 If you were to create a graph of this piecewise function, which point would have an open circle? (1 point) Responses (0,0) left parenthesis 0 comma 0 right parenthesis (1,2.5) left parenthesis 1 comma 2.5 right parenthesis (10,25) left parenthesis 10 comma 25 right parenthesis (10,22.5) left parenthesis 10 comma 22.5 right parenthesis
The point that would have an open circle on the graph of the piecewise function is (10, 22.5) because at x = 10, the function is defined as f(x) = 2.25x which means that the y-value at x = 10 is 22.5. Since the function is defined for x ≥ 10, the point (10, 22.5) has an open circle indicating that it is not included in the graph.
