Answer:

Option D.

Step-by-step explanation:

A relation is called a function if there exist a unique output for each input.

Vertical line test : The graph of a function intersect each vertical line almost once.

If the graph passes vertical line test, then it is a function otherwise it is not a function.

From the given graphs it is clear that graph first three graphs intersect the vertical line more than once, therefore they are not functions.

Last graph passes the vertical line test, therefore it is a function.

Hence, the correct option is D.

Determine whether each of these functions is O(x^2 ).

otez555 [7]

Answer:

(a) no
(b) yes
(c) no
(d) no

Step-by-step explanation:

"Of the order x^2" means the dominant behavior matches that of x^2 as x gets large. For polynomial functions, the dominant behavior is that of the highest-degree term.

For other functions, the dominant behavior will typically be governed in some other way. Here, the rate of growth of the x·log(x) function is determined by log(x), which has decreasing slope as x increases.

Only answer selection B has a highest-degree term of x^2, so only that one exhibits O(x^2) behavior.

Brandon bought 6 toy cars. The cars came in p packages. Write an expression that shows how many toy cars were in each package.

Readme [11.4K]

Well in order to find how many toy cars were in each package you would need to divide the number of toy cars by the number of packages. So your expression would be p / 6.
