Question

The cost of a watermelon depends on its weight which of the following shows this idea expressed in function notation

A: weight(cost)

B: cost(watermelon)

C: cost(weight)

D: weight (watermelon)

Answer 1

That would be choice C, cost as a function of weight.

Answer: C

Answer 2

Option C is correct.

Explanation:

The general form for writing a function of x is f(x) where f depends on value of x.

Here, in the given options, Option C is correct as weight is a function for cost. The cost depends on the weight. The more the weight of the watermelon, the more its cost. So, C: cost(weight) is correct.

Options B and D are irrelevant and option A is also wrong as it signifies that weight depends on cost which is wrong.
