Question

1. What does the 15 represent in the equation? 2. What does the 80 represent?3. Is this a discrete or continuous function? 4. At this rate, how much would it cost to buy 25 inks? 5. What is the domain and range of the function

Answer 1

Step-by-step explanation

Since the printer cost $80 and we need to pay $15 for each ink cartridge, we can apply the following relationship:

`C(n)=15n+80`

1) The number 15 represents the slope of the equation.

2) The number 80 represents the y-intercept

3) This is a discrete function.

4) y = 15*25 + 80

Multiplying terms:

y = 375 + 80

Adding numbers:

y = 455

It will cost $455 to buy 25 inks.

5) Domain: {0,1,2,3,4}
