i think the graph g(x) has been shrunk vertically by a factor of 1/5 and shifted up by 4 units :)
A.) 135 miles in 3 hours = 45 miles per hr
B.) 22 miles in 1 hour= 22 miles per hr
C.) 7.5 miles in 1/4 hour = 30 miles per hr
D.) 100/3 in 2/3 hour = About 49.9 mph
E.) 97.5 in 1.5 hours = 65 miles per hr
True. When the points are plotted on a graph and connected, they pass the vertical line test. No x value is the same.
