Question

Which of the following statements are not true regarding functions?

Answer 1

Answer:

(B) A function is a relation in which each value of the input variable is

paired with at least one value of the output variable.

(D) The vertical line test may be used to determine whether a function

is one-to-one.

Both of these are incorrect/false statements

(I used these in my test on Apex and got both correct)

This means that if the question was reversed and asking about the statements are true, the answers would be:

(A) A sequence is a function whose domain is the set of natural

numbers.

(C) The horizontal line test may be used to determine whether a

function is one-to-one.
