6. customers at the palace pro shop receive a 20% discount if they are members. all customers

must pay 7% in sales tax. the function f(x) = 0.8x is used to determine the price of an item after the

20% member discount, wherex is the regular price of the item. the function g(x) = 107x is used to

determine the total amount customers pay for a purchase after all discounts are applied. which

function can be used to determine t(x), the total amount a member pays for an item with a regular

price of x dollars?

Total amount for an item would be 85.6x.

Step-by-step explanation:

Since we have given that

Rate of discount = 205

Rate of sales tax = 7%

Function f(x) is used to determine the price of an item after the 20% member discount is given by

Function g(x) is used to determine the total amount customers pay for a purchase after all discounts are applied which is given by

we will use composite function gof(x) to find the total amount a member pays for an item with a regular price of x dollars.

Hence, total amount for an item would be 85.6x.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
