Determine the range of the function? Y=2x(squared) +3
A.all real numbers
B.all integers less than or equal to 3
C.all integers greater than or equal to 3
D.all real numbers less than or equal to 3

Respuesta :

The range of y = x^2 is the set of nonnegative numbers. The same applies to y = 2x^2 as well. Shift everything up three units to get y = 2x^2+3

So the range is the set of numbers y such that [tex]y \ge 3[/tex]

The final answer is choice C.
