All you can remember is to travel 5 miles then turn in a new direction (you are not sure in which direction) for another 4 miles. what is the minimum distance you must travel?

distance = 5+4 = 9 miles

(distance that a person travel)

displacement = 5-4 = 1miles

(displacement is the distance between the starting point and ending point)

distance≠displacement

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

b. f(x) = –√x + 3this is the correct answer
