Percentage increase in the rate of all rail season tickets to London = 4% Price of the rail ticket from Cambridge to London increased by = 121.60 Let us assume the price before the increase in the fare = x Then 4% * x = 121.60 dollars (4/100) * x = 121.60 dollars x/25 = 121.60 dollars x = 25 * 121.60 dollars = 3040 dollars So the price of the ticket from Cambridge to London before the increase in price was 3040. I hope the procedure is simple enough for you to understand.
A. The graph of the function is vertically shrunk by a factor the graph of the function so the domain and the range of both functions are the same. This option is false.
B. The graph of the function is vertically shrunk by a factor the graph of the function so the domain and the range of both functions are the same. This option is true.
C. The graph of the function is translated 2 units to the right and vertically shrunk by a factor the graph of the function so their graphs are similar except the first graph is shifted right and shrunk vertically by a factor of . This option is true.
D. The function has the domain and the range all non-negative real values. The function has the domain and the range all real values. So this option is false.
