Write a function rule using function notation that will transform a geometric figure by a dilation of 3. O fix, y)= (-3x, -3y) O f(x y)= (3x, y) O fx v)= (x. 3y) O f(x, y)=(3x, 3y)

7. Identify whether the following ordered pairs is a function: (2, 2), (3, 2), (5, 4).

answer the question in a grade 11 functions matter

Given that A = {1, 2, 3, 4, 5} and B = {x, y, z}, determine which of the sets of ordered pairs represents a function from A to B. Explain the reason(s) why or why not for each i)  {(1, z), (2, x), (3, y), (2, x)} ii)  {(1, z), (3, y), (2, x), (4, x), (5, 5)} iii)  {(1, y), (2, y), (5, x), (3, y), (4, y)} Which of the following graphs represent y as a functionof x? Explain the reason(s) why or why not for each ii)
