Consider the following statement. If x is nonnegative, then x is positive or x is 0. In (a)-(d) below, select the negation, contrapositive, converse, and inverse for the statement. (Assume that all variables represent fixed quantities or entities, as appropriate.) (a) Negation O fxis not positive and x is not 0, then x is not nonnegative. O fx is positive or x is 0, then x is nonnegative. O fxis not nonnegative, then both x is not positive and x is not 0. O fxis not nonnegative, then x is positive or x is 0. O xis nonnegative and x is not positive and x is not 0. (b) Contrapositive O fxis not positive and x is not 0, then x is not nonnegative. O ffx is positive or x is 0, then x is nonnegative. O fxis not nonnegative, then both x is not positive and x is not 0. O fxis not nonnegative, then x is positive or x is 0. O xis nonnegative and x is not positive and x is not 0. (c) Converse O fxis not positive and x is not 0, then x is not nonnegative. O fxis positive or x is 0, then x is nonnegative. O fxis not nonnegative, then both x is not positive and x is not 0. O fxis not nonnegative, then x is positive or x is 0. O xis nonnegative and x is not positive and x is (d) Inverse O fxis not positive and x is not 0, then x is not nonnegative. O fx is positive or x is 0, then x is nonnegative. O fxis not nonnegative, then both x is not positive and x is not 0. O fx is not nonnegative, then x is positive or x is 0. O xis nonnegative and x is not positive and x is not 0.
