Concept explainers
To write if-then form, the converse, the inverse, the contrapositive, and the biconditional of the given conditional statement.
Answer to Problem 10CT
If-then form conditional statement:
If relation is a function then each input has exactly one output.
The converse of a conditional statement:
If each input has exactly one output then relation is a function
The inverse conditional statement:
If relation is not a function then each input does not have exactly one output.
The contrapositive conditional statement:
If each input does not have exactly one output then relation is not a function.
The biconditional of the conditional statement:
Relation is a function if and only if each input has exactly one output.
Explanation of Solution
Given information:
The conditional statement given is
A relation that pairs each input with exactly one output is a function
Concept used:
If-then form conditional statement:
When a conditional statement is written if-then form the “if” part contains the hypothesis and the “then” part contains the conclusion.
The converse of a conditional statement:
To write the converse of a conditional statement, exchange the hypothesis and the conclusion.
The inverse conditional statement:
To write the inverse of a conditional statement, negate both the hypothesis and the conclusion.
The contrapositive conditional statement:
To write the contrapositive of a conditional statement, first write the converse. Then negate both the hypothesis and the conclusion.
The biconditional of the conditional statement:
When a conditional statement and its converse both are true, it can be written as a single statement using phrase “if and only if” it is called biconditional statement.
If-then form conditional statement:
If relation is a function then each input has exactly one output.
The converse of a conditional statement:
If each input has exactly one output then relation is a function
The inverse conditional statement:
If relation is not a function then each input does not have exactly one output.
The contrapositive conditional statement:
If each input does not have exactly one output then relation is not a function.
The biconditional of the conditional statement:
Relation is a function if and only if each input has exactly one output.
