4: What is the domain for the following function? Y = 4/x^2 + 1 A: (x 3) B: (x 0) C: (all real numbers) D: (x - 3) 5: What is the range for the following function? 1 y = ------ + 2 x + 3 A: {y: y R, y 2} B: {y: y R, y 3} C: {y: y R) D: {y: y R, y - 2} If you do not recognize the in this equation that is because it is being used in replace of a similar looking shape, likewise though I doubt it has a big influence on the outcome of the answer. 7: Which function does not have a vertical asymptote. A: y = 5x 1/x B: y = x/1 + x^2 C: y = 5x/1 x^2 D: y = 5x/x + x^2
