What are the domain and range of
d range of f(x) = ( 1)* + 2?
domain: {xix> -1}; range: (y ly > 0}
domain: {x\*> *), range: {yly > 2}
domain: {x | x is a real number}; range: {yly> 2}
domain: {x|x is a real number}; range: {yly > -2}

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
