topping?

c. What will be the domain and range of the problem?​

Answer 1

Step-by-step explanation:

Given At Joe's pizzeria a pizza cost $5 with the first topping, and then an additional 75 cents for each additional  topping  

a. If x represents the number of toppings on a pizza, What function represents the cost of a pizza with at least one  topping?

b. What will be the function rule of the problem?

c. What will be the domain and range of the problem?​

• According to the question the cost for one topping keeps on changing and there will be a constant rate of change.
• We have the slope intercept y = mx + b
• Now when x = 0, y = b
• But cost of pizza is $ 5, therefore we have
•                              5 = m(0) + b
•                            Or b = 5
• Since m is the slope and each additional topping costs 75 cents we get m = 0.75 (since the unit is changed from dollar to cents)
• Also we have the additional toppings will cost 75 cents and only the first topping is $5 price.
• Now one less than the number of toppings will be x – 1
• Now we can write the function as  
•                              f(x) = 0.75 (x – 1) + 5
