Question

For each relation represented by the graph, determine whether a. r and justify your answer. y is a function of (Click on the graph to get a larger version.) Is y a function of ? ? B The reason for my answer is A. The graph is continuous and has no sharp corners B. At least one value of x has more than one y value associated with it C. For some values of y (like 6), the graph shows multiple values of z associated with it 0 D. For every value of 2, the graph shows exactly one associated value of y b. (Click on the graph to get a larger version.) Is y a function of x? The reason for my answer is.. A. For every value of y, the graph shows exactly one associated value of a B. Every value of z shown by the graph has exactly one y value associated with it C. The graph is discontinuous and has a sharp corner D. For some values of (ike 16), the graph shows no value of y associated with it

Explanation / Answer

a) yes y is a function of x because

graph is continious and for some values of y graph shows multiple values of x

like for y=6 , y=5, y=7 and more there are multiple values of x

so option C

b) no y is not a function of x because

for some values of , there is no value of y

so option D
