In the function showing the cost for any number of apples, what is the input or x-value? a. cost b. the price per pound c. the number of apples per pound d. number of apples

D.) The number of apples

Step-by-step explanation:

The input, or x-value, will always be an independent variable. The output, or y-value, is a dependent variable-- it's value depends on what the input is.

The cost is dependent on how many apples you buy.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
