Hich of the following could not be true for a function? domain is {2}, range is {2} domain is {2, 3}, range is {2} domain is {2}, range is {2, 3} domain is {2, 3}, range is {2, 3}

Step-by-step explanation:

C

if it is a function then one value of domain can not give two values of range.

so C is not true.

X - .4x

Step-by-step explanation:

X - .4x = x(1-.4) = .6x

1 -0.4x  These are not like terms so they cannot be combined

X + 0.6 These are not like terms so they cannot be combined

0.6X - X  x( .6-1) = x(-.4) = -.4x
