Answer 3

A phone company charges its customers as follows:
For the first 500 minutes used each month, the customer is charged a flat rate of $50. These 500 minutes are "included" in their monthly plan.
For any additional minutes used, the customer is charged an additional $.10 per minute.
Which type of function would best model this situation: a greatest integer function or a piecewise function that is not a greatest integer function? Explain.

Answer 4

Uhh.. dunno if it's what you're asking.. but to find the total cost:
x(.10)+50=y, when x= the number of extra minutes used, and y= the total cost

Answer 5

Did that help at all? @Nnesha

Answer 6

is that step function or piecewise function

Answer 7

i'm soryy i didn't understand can you explain it a little bit more

Answer 8

It is neither.
It is the formula to solve for the total cost.

Answer 9

I am unsure what a step functions or piecwise functions are. Never heard those terms.

Answer 10

ok what about this one

Answer 11

A local utilities department is responsible for billing its town's citizens for their water usage each month. The amount of each household's bill is determined by the number of gallons of water they use monthly. For example, If a household uses between 1000 and 2000 gallons of water, their bill will be $57. However, if they use between 2001 gallons and 3000 gallons, their bill will be $72.
Which type of function would best model this situation: a step function or a piecewise function that is not a step function? Explain.

Answer 12

Hmm, well I looked up the definition of step function:
a function that increases or decreases abruptly from one constant value to another.

Answer 13

And for piecewise function:
a piecewise-defined function (also called a piecewise function or a hybrid function) is a function which is defined by multiple sub functions, each sub function applying to a certain interval of the main function's domain (a sub-domain).

Answer 14

Which one of those fits the situation better?

Answer 15

step function i guess?/

Answer 16

anybody ????????????????????????????/
