Direction: Solve the following problems using a separate sheet of paper. Choose the letter of the correct answer from the choices given below and decode the secret message. 1. If f (x) = 3x - 1 and g(x) = -2x + 4, find (f - g) (x). 2. If j (x) = 3x2 + 8 and k(x) = x2 - 7, find (j + k) (x). 3. If m(x) = 4x - 5 and n(x) = 2x2 - 3, find (m on) (2). 4. Given b(x) = x + 8 and d(x) = x - 9, find (b . d) (-3). 5. Given p(x) = x2 - 36, and q(x) = x + 6, find (P) (x). 6. If w(x) = x3 - 2x2 - x+ 1, find w(-2). 7. If v(x) = 8x-3 1, find v(3) 8. The underground temperature in degree Celsius, a basis for geothermal energy source can be approximated by using the function T(d) = 35d + 20, where d is the distance from the land surface in km. Find the underground temperature 3,500m below the surface. 9. Under the new fare scheme of the Land Transportation Franchising and Regulatory Board (LTFRB), the flag down rate for taxis remains at P40 but the distance rate is now at P13.50 per kilometer. Using the function r (d) for the taxi rate where d is the distance traveled, write a piecewise function for this scenario. How much will a passenger pay for a 14.5 - kilometer ride?
