Circle q has radius qr of length 55 cm. point p is 73 cm. from q, and pr is a tangent segment. how long is pr? a. 18 cm. b. 48 cm. c. 64 cm. d. 128 cm.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

what i would say the best answer is a. 40.5
