Help me please with complete solution in a paper thank you

Performance Standard. The learners: represents real-life situations using functions, including piece-wise functions. M11GM-la-1; evaluates a function. M11GM-la-2. PART 1. CHOOSE RIGHT. Select the letter of your best answer and write it on the space provided on the number. USE PENCIL in accomplishing this sheet. Two points each. Best of luck! 1. What is a rule that corresponds to sets of values from the domain to another set of values called range? A. Domain C. Function B. Range D. Relation 2. Tim sells turon at Php15.00 each. What is the function notation f(x) for his sales if he sells x pieces? A. f(x) = 15 C. f(x) = 15+x B. f (x) = x-15 D. f (x) = 15x 3. A certain chocolate bar costs P40 per piece. However, if you buy more than 20 pieces, they will be marked down to a price of P35 per piece. Which from the piecewise functions below represents the revenue in terms of the n number of chocolate bars bought? A. f(n)= 40n ,if OSn s 20 .if OSn57 35n .if n > 20 C. f(n) =" 35n ,if n>7 B. f (n ) = " if OSn57 (35n ,if OSns5 35n , if n> 7 D. f(n)= 120n ,if n > 5 4. Given f(x) =2x+1 , evaluate f(2). A. 1 B. 3 C. 5 D. 8 5. Which of the following is an exponential function? A. f(x) = 4x+8 B. f(x) = 42' +8 C. f(x) = 4x'+8 D. f (x)= 4x+8 PART 2A. LET'S TRY IT. A tricycle TODA in a city charges Php20.00 for the first 5 ks. Then they charge Php 5.00 for every kilometer for distance (n) more than 5 km. Finally, they charge a flat rate of Php300.00 for more than 20 kilometers. Write the peicewise func- tion for the fare represented by f(n) where n is succeeding distance in kilometers. Five points. Attach a separate sheet if needed. The final answer is complete. 4-5pts The final answer lacks minor 3-4 pts The final answer and illustration 2-3 No effort at all 0-2 pts The piecewise fuction is well details. The piecewise function lacks major details. The piecewise pts presented. not well presented. fuction is poorly presented. PART 2B. LET'S SOLVE. Based from the above problem (2A), if Jojo would ride the tricycle and the distance from his location to a Crystal Wave, Talavera is 32 kilometers, how much should he pay? Show your solution and final answer below. Write your reason if necessary. Five Points. Attach a separate sheet if needed. Solution and final answer are 1-5pts The final answer lacks minor 3-4 pts The final answer and illustration 2-3 No effort at all 0-2 pts complete and/or explanation is details. The piecewise function lacks major details. The piecewise pts evident not well presented. fuction is poorly presented
