Function C gives the cost, in dollars, of buying n apples. What does each expression
or equation represent in this situation?
a. 8) = 4.50
b. C(2)

Answer:

The question is not detailed enough as the expression of the distance as a function of time is missing.

Step-by-step explanation:

But we can still assume an expression for the distance as a function of the time in seconds.

  • Say F (distance) = xt + y

  • This implies that for every value of the distance, you substitute the value given for time.
  • Generate a simultaneous equation with two unknowns by getting the constants (x and y)
  • Then go back and plug it in the original equation and start the substitution.

  • Similarly for Cost C as a function of the number of apples bought, the same approach will be used to generate the general equation linking the two terms together.

a) 8) = 4.50 implies the time in seconds as against the distance of the dog from the post.

b) C(2) - This expression represents the cost of two apples, ere the number of apples is known
