Quiz #1

Name:___________________________ Date:____________________

Section:__________________________

Instruction: Answer the following question, use extra paper if needed. GoodLuck😊

A. Function or Not Function


1. f = {(1,2),(2,3),(3,5),(4,7)}

2. g = {(1,3),(1,4),(2,5),(2,6),(3,7)}

3. f = {(1,3),(2,6),(3,9), … (n,3n), …}
4. __________________ 5. __________________

B. Identify the domain for each relation.

6.) f = {(0,2),(2,3),(3,5),(4,7)}

7.) g = {(1,3),(1,4),(2,5),(2,6),(3,7)}

8.) f = {(1,3),(2,6),(3,9), … (n,3n), …}

9. __________________ 10. __________________

11.) y = 2x+1

12.) y = √ x+ 2

13.) A certain chocolate bar costs P35.00 per piece. However, if you buy more than 10 pieces, they will be
marked down to a price of P32.00 per piece. Use a piecewise function to represent the cost in terms of the
number of chocolate bars bought.

14.) A school’s fair committee wants to sell t-shirts for their school fair. They found a supplier that sells t-
shirts at a price of P175.00 a piece but can charge P15,000 for a bulk order of 100 shirts and P125.00 for
each excess t-shirt after that. Use a piecewise function to represent the cost in terms of the number of t-
shirts purchased.
C. Evaluate the following functions at X = -4
