- If the point (3,4) is on the graph of the function f , then the point ( __ , __ ) Is on the graph of f1 .arrow_forwardWhich of the following are graphs of functions? If the graph is that of a function, is itone-to-one?arrow_forwardIn this problem you are asked to find a function that models in real life situation and then use the model to answer questions about the guidelines on page 273 to help you. Minimizing Time A man stands at a point A on the bank of a straight river, 2 mi wide. To reach point B, 7 mi downstream on the opposite bank, he first rows his boat to point Pon the opposite bank and then walks the remaining distances x to B, as shown in the figure. He can row at a speed or 2 mi/h and walk as a speed of mi/h (a) Find a function that models the time needed for the trip. (b) Where should he land so that he reaches B as soon as possible?arrow_forward
