Which quadratic function does not have the domain and the range

y 6?

y = 6(x – 4)(x – 2)
y = 0.5(x – 3)2 – 6
y = 0.5x2 – 2x – 4
y = x2 – 2x – 6

would it be the last one ?

Question

Which quadratic function does not have the domain  and the range
 
y  > 6?   


y = 6(x – 4)(x – 2)
y = 0.5(x – 3)2 – 6 
y = 0.5x2 – 2x – 4

And the domain of all of them is all real numbers so I think you have posted something incorrectly.

yes just one sec i just noticed 

Which quadratic function does not have the domain X$$\epsilon$$ Real numbers  and the range y  > 6?

y = 6(x – 4)(x – 2) 
y = 0.5(x – 3)2 – 6 
y = 0.5x2 – 2x – 4 
y = x2 – 2x – 6

anonymous · Answer

the X equalls to all real number

ok thank you

mertsj · Answer

yw.  You posted something wrong.

mertsj · Answer

Actually the last one has range y >=-7
