How do I do the bus stop method?
hichkok12 [17]
The bus stop method is just like division.
Ex
137÷5= 
1.) 5 goes into one zero times so there is a zero on top.
2.) 5 goes into 13 two times, so after the zero there is a 2.
3.) 5 goes into 37 seven times so there is a 7 after the 2.
4.) There is a 2 left and five can't go into school therefore that is a remainder.

Which of the following statements are not true regarding functions?
MArishka [77]

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.
