Final answer:
The one unit growth factor between the given points (0, 21) and (1, 63) is 3, indicating the y-value triples with each unit increase in x.
Step-by-step explanation:
The one unit growth factor between the points (0, 21) and (1, 63) on the xy-plane can be calculated by taking the ratio of the y-values of these points. To find this, divide the y-value at x=1 by the y-value at x=0.
To calculate: One Unit Growth Factor = (Value at x=1)/(Value at x=0) = 63/21 = 3.
Therefore, the one unit growth factor is 3, which means for every unit increase in x, the y-value is tripled.
The growth factor can be determined by finding the ratio of the y-coordinates of the two points, which represents the change in the y-coordinate for a one unit change in the x-coordinate. Taking the second point (1, 63) and dividing the y-coordinate by the x-coordinate gives a growth factor of 63/1 = 63.
So the one unit growth factor is 63.
