Question

The cost to rent a paddle board for a different number of hours is shown. Is the cost a function of the rental time?

A. No, since there are two inputs (Time in hours) which have the same cost (in dollars).

B. No, since there are two costs (in dollars) which have the same inputs (time in hours)

C. Yes, since each output (cost in dollars) has a single input (time in hours)

D. Yes, since each input (time in hours) has a single output (cost in dollars)

Answer 1

I think the answer is a

Answer 2

No, since there are two inputs (time in hours) which have the same cost (in dollars). Therefore, option A is the correct answer.

Step-by-step explanation:

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

From the given that,

(1, 25), (2, 45), (3, 45) and (4, 55)

It is not a function as two inputs 2 and 3 has a single output 45.

That means A is correct, i hope you have a good day random person :)
