Let's Apply I. Determine whether the following functions are rational or not. Explain why. 1./(x) - 9 2/(x) - 3- 1+4 3./0) - 1414 4/(x) - 2+ 10 5. f(x) = 4x+x2 4x +2 [Type here] General Mathematics: Quarter 1 Week 2 II. Direction: Complete the table below using the given information. Given an equation modeling the annual sales S (in millions of units) of a certain computer model t years after its release, you are to determine the time it will take before the 30 - 6x public stops buying their product. This equation is given by 6 -x . The first one is done for you. 2 5 6 7 S= 4.8M 6-1 In what sales do you think will the sales be below 3 million? Let's Analyze Direction: Analyze and answer the following problems. 1. The numerator of a fraction is 4 less than its denominator. If both the numerator and the denominator of the fraction are increased by 2, then the resulting fraction is equal to 3/5. What is the fraction? Write an equation that will represent the problem. 2. Paulo drove 75 kim from Tanauan, Batangas to Lucban, Quezon to visit his cousins. His average speed for the trip to Lucban was 10 km/h faster than on his way back to Tanauan, and as a result, his return trip took 2 hours longer. What is his average speed for the trip to Lucban? Write the equation that will represent the function. IV Let's Evaluate D Solve for the unknown value. Show your solution - 3 x -s 9941 2. x2+3x x+3 x- + 3x x+ 3 2x Let's Create Direction: Read the problems carefully and construct the table of values and graph. 1. Represent the rational function given by *+ 1 using table of values. Plot the points in Cartesian plane and connect the points. Use values of x from -10 to 10. Table of values f(x) 6
