The chart below lists the original and sale prices of items at a clothing store. clothing prices original price sale price $7.99 $5.59 $10.99 $7.69 $12.99 $9.09 $15.99 $11.19 $24.99 $17.49 $29.99 $20.99 which statement best describes why the sale price is a function of the original price?

The correct answer is C. For every original price, there is exactly one sale price.

100% correct.

I just took the quiz.

Hence sales price is a funcition of original price

Step-by-step explanation:

A function is a mapping in which every element in the domain has a unique image in the co domain.

From the chart we find that for each clothing price, there is a unique selling price given.

This implies the mapping from original price to selling price is a function.

Also we find that there is an association between the two prices.

Whenever  original price increases, sales price also increases thus confirming the positive relationship between the two

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
