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 Σ R, y ≠ 2}
B: {y: y Σ R, y ≠ 3} 
C: {y: y Σ R) 
D: {y: y Σ R, y ≠ - 2}
If you do not recognize the Σ 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
