Consider the following graph of a piecewise-defined function. when x< -2, f(x)= a: -3 b: 5 c: 2 when -2 a: x+2 b: 2x+2 c: 2x when x> 3, f(x)= a: -3 b: 5 c: 2

State whether weight is a function of height for the six students and explain. a. yes, height is a function of weight because two students weigh 165 pounds but have different heights. b. no, height is not a function of weight because two students weigh 165 pounds but have different heights. c. yes, weight is a function of height because for each value of height there is one corresponding value of weight. d. no, weight is not a function of height because there is not enough data to determine a function.
