Albert has $105 to spend, the prices varying from $80 to $180 worth delivery being one-twentieth of the price. total cost can be modeled by the function f(c) c representing the price. domain is:

Answer

Domain=[80, 100] ie. both of them inclusive.

Step-by-step explanation:

Albert has total $105.

Let the cost of a product be c.

Therefore, the total cost of a product after the delivery and all is represented by a function f(c)

f(c)=c+

f(c)=

The domain, of the function is the no. of possible values of c that can satisfy the equation.

Now, lets check the maximum price of the product that Albert can buy.

f(c)=105

=105

c=$100

As, the minimum price of a product of is $80 , the domain needs to start from here. And it will go on till $100.

Domain=[80, 100]

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

noncoplanar points are points that do not lie on the same line.
