I got the following two questions wrong. What is the correct answer and why?

Incorrect: 0/8 Pts

Why is the function f:R R defined by f(x) = sqrt(x) not well defined?

a. This function is well defined.

b. Some elements in the domain map to more than one element in the range.

c. Some elements in the domain do not map to an element in the range.

Two sets A and B are defined as

A = {a, b, c, d}

B = {1, 2, 3}.

Let the function f: A B be defined as

f = {(a, 1), (b, 2), (c, 1), (d, 1)}.

What are the

Domain:

Range:

Target:

Drop down possible answers shows the following:

{a, b}

{a, b, c, d}

{1, 2}

{1, 2, 3}
