Research performed at the national health research project illustrates that speed at which the blood cell travels in the artery depends on the distance from center of artery. Function v=1.19-1.87r^2 models velocity (in cm/sec) of the cell which is r cm from center of artery.
a) Determine graph of v which reflects values of v suitable for theproblem. Record window viewing dimensions.
b) If the blood cell is travelling at 0.975 cm/sec, find distance blood cell is from center of artery.
