A design model uses C(x)=(4x - 1)(x + 2), where x is restricted to x>=0. Which statement correctly interprets C(x)=0?
A
The algebraic zeros are x=-1/4 and x=2, but only x=2 is meaningful in the restricted domain.
B
The algebraic zeros are x=1/4 and x=-2, but only x=1/4 is meaningful in the restricted domain.
C
The only algebraic zero is x=4 because the factor 4x - 1 has coefficient 4.
D
There are no zeros because x must be nonnegative.
