The graphs of the equations y=x^2 and y=k-x^2,where k is a constant,are shown above.If the length of AB is an integer,which of the following CANNOT be the value of A 2 B 8 C 12 D 18 E 32
The graphs of the equations y=x^2 and y=k-x^2,where k is a constant,are shown above.If the length of AB is an integer,which of the following CANNOT be the value of
A 2 B 8 C 12 D 18 E 32
The graphs of the equations y=x^2 and y=k-x^2,where k is a constant,are shown above.If the length of AB is an integer,which of the following CANNOT be the value of A 2 B 8 C 12 D 18 E 32
k-x2=x2
x2=k\2
Because the length of AB is integer,then the value of x is integer,and so k\2 can not be 12.
