which of the following statements are not true regarding
functions?

A. True. If it is possible to pass a single horizontal line through more than one point on the function curve, then the function is not one-to-one (it fails the horizontal line test).

B. True. Any given input must lead to exactly one output.

C. False. The vertical line test is used to determine if a relation is a function or not.

D. False. The domain of a sequence is the set of natural numbers {1, 2, 3, ...}

In summary, the answers are A and B

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
