3. For the following graphs, use the vertical line test to determine whether the graph represents a function. Also, find the domain and range. 3 a) 2 -4 -3 -2 -1 1 -1 -2 -3 c) -4 -3 12 function? D: _ 3 R: 3H b) 2 -4 -3 -2 -1 1 2 3 -1 -2 -3 function? 4 D: R: function? D: function? d) 3.5 3 3+ 2.5 D: 2 1.5- -2 -1 2 3 4 1+ -1 R: 0.5 -21 -2 -1 1 2 3 4 5 67 8 0.5 3 -1 R: 3.
